A bag contains chips of which 27. 5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement. What are the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 ?.
Answer:
No. of blue chips contain in a bag = P = 27.5 % = 0.27
No. of chips random selected at a time with replacement = n = 5
We know that the mean and standard deviation of the sampling distribution of the sample proportion (p) is given by :-
\mu\-_pμ\-p = p
= 0.275
\sigma_pσp = \sqrt{\frac{p (1-p)}{n} }np(1−p)
Where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
= \sqrt{\frac{0.275 ( 1 - 0.275)}{5} }50.275(1−0.275)
= 0.1997
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.
What is the mean and standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.
A bag contains chips of which 27.5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement.
Then the mean is given as,
Mean = 0.275 x 5
Mean = 1.375
Then the standard deviation is given as,
Standard deviation = √[5 x 0.275 x (1 - 0.275)]
Standard deviation = √0.99687
Standard deviation = 0.9984
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.

The second lap that Caroline ran lasted 10.3 minutes.
Speed is the ratio of distance to time taken. It is given by:
Speed = distance / time
Since the distance of the lap is 1.2 km. The second lap was at an average speed of 7 km/h. Hence:
7 = 1.2 / time
time = 10.3 minutes

Answer: A Binomial distribution apply when we have n identical and independent events with two possible results, success or fail, and a probability p of success and 1-p of fail. Then, the probability that from the n events, x are success is:
Then, the number of motorist driving more than 5 miles per hour over the speed limit follow a Binomial Distributions, because we have 4 randomly selected motorists with two possible options: they are driving more than 5 miles per hour over the speed limit or they aren't, and the probability that they are driving more that 5 miles per hour over the speed is 0.4.
Finally, the probability P that among 4 randomly selected motorists, the officer will find at least 1 motorist driving more than 5 miles per hour over the speed limit is:
P = P(1) + P(2) + P(3) + P(4)
Where n is equal to 4 and p is equal to 0.4. Replacing the values for every x, we get:
Finally, P is equal to:

What has the smallest effect on the rate of photosynthesis.
Answer:
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
The smallest effect on the rate of photosynthesis is typically the availability of carbon dioxide (CO2).
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen.
Other factors that can influence the rate of photosynthesis to a greater extent than carbon dioxide include:
Light intensity: The rate of photosynthesis increases with higher light intensity, up to a certain point. Beyond that point, called the saturation point, increasing light intensity does not further increase the rate of photosynthesis.
Temperature: Photosynthesis is a temperature-dependent process. Within an optimal temperature range, the rate of photosynthesis increases with higher temperatures.
Water is essential for photosynthesis as it provides the medium for chemical reactions to occur. Inadequate water availability can lead to a decrease in photosynthesis.
Therefore, while all the factors mentioned (light intensity, temperature, water availability) can significantly impact the rate of photosynthesis, the availability of carbon dioxide generally has the smallest effect.

Which of the following would have the largest concentration of chloride ions in solution.
Answer:
From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions.
To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.
1) 0.10 M MgCl₂
We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:
Hence, in this solution we have 0.20 M of chloride ions.
2) 0.10 M AlCl₃
In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:
Then, the concentration of chloride ions in this solution is 0.30 M.
3) 0.05 M CaCl₂
We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:
So, the concentration of the Cl⁻ ions is 0.10 M.
4) 0.10 M LiCl
In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:
Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.
Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.
