A class in New Zealand found a report suggesting that teenagers' heights in New Zealand are approximately
normally distributed with a mean of 160 cm and a standard deviation of 15 cm. They thought the mean height
at their school was probably larger, so they took a random sample of n = 24 students. The mean height of
students in their sample was Ž = 166.5 cm.
To see how likely a sample like theirs was to occur by random chance alone, the class performed a simulation.
They simulated 80 samples of n = 24 heights from a normal population with a mean of 160 cm and standard
deviation of 15 cm. They recorded the mean of the heights in each sample. Here are the sample means from
their 80 samples:
Answer:
p-value≈0.025
Step-by-step explanation:
Khan Academy
From the stimulated results, the p-value of the test will be 0.025.
What is a p-value?It should be noted that a p-value simply means a measure of the probability which an observed difference could have occurred by random choice.
In this case, the class took a random sample of n = 24 students and the mean height of students in their sample was Ž = 166.5 cm.
The p value of 0.025 indicates that the hypothesis fails to account for the facts that were presented.

A bakery sells cupcakes and cookies. No more than 750 total items
can be produced a day. Production costs cannot exceed $1200 per day. It costs
$0.50 to make a cupcake and $0.25 to make a cookie. Given that you have the
constraints0.5x +0.25y < 1200 and 2 + y < 750, how would you
write an additional constraint to represent that the bakery can produce at most 85
cookies?
Answer:
The question doesn't make since so random guess
If you multiply $0.50 by 750 you get 375
If you multiply $0.25 by 750 you get 187.5
divide that by 85 and you get 2.2.

Find the volume of this sphere.
Use 3 for TT.
V V ~ [?]cm3
V = nr3
r=6cm
Answer:
[tex]V = 864cm^3[/tex]
Step-by-step explanation:
Given
[tex]r = 6[/tex]
[tex]\pi = 3[/tex]
Required
The volume of the sphere
This is calculated as:
[tex]V = \frac{4}{3} \pi r^3[/tex]
So, we have:
[tex]V = \frac{4}{3} *3 *6^3[/tex]
[tex]V = \frac{4}{3} *3 *216[/tex]
This gives:
[tex]V = 4 *216[/tex]

Please help due today!!
Answer:
C) 25
Step-by-step explanation:
First, solve for the height (red dotted line) using the Pythagorean theorem 9²+b²=15²
81+b²=225
b²=225-81
b²=12
Then set up a ratio.
x/12=9/15
simplify
x/12=3/5
cross-multiply
3x=60
x=20
This gives us the base. Now we can solve for x using the Pythagorean theorem again.
20²+15²=x²
400+225=x²
625=x²
√x²=√625
x=25
Suppose you roll two 8 sided dice.
a.) What is the probability of rolling a sum of 4?
b.) What is the probability of rolling a pair of ones?
c.) What is the probability of rolling two odd numbers?
Can anyone help me?
Answer:
Step-by-step explanation:
A)
You can roll a four in the following 3 ways
2 2
1 3
3 1
If the dice are fair and you can roll any one of 8 numbers then the the total number of ways that you can roll 2 eight sided dice is 8 * 8 = 64
Answer 3/64 or 0.0469
B)
You can roll a pair of ones only 1 way.
1/64 = 0.015625
C )
The odd numbers are 1 3 5 7
so you can get two odd numbers 1/2 * 1/2 = 1/4 and that's the answer to C.

Suppose that you take a random sample of 259 people leaving a grocery store over the course of a day and find that 12% of these people were overcharged. Find a 95% confidence interval for the actual percentage of shoppers who were overcharged.
a. 5.7% to 18.3%
b. 8.85 to 15.15%
c. 7% to 17%
d. 9.5% to 14.5%
Answer:
8.04% to 15.96%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
Suppose that you take a random sample of 259 people leaving a grocery store over the course of a day and find that 12% of these people were overcharged.
This means that [tex]n = 259, \pi = 0.12[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 - 1.96\sqrt{\frac{0.12*0.88}{259}} = 0.0804[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 + 1.96\sqrt{\frac{0.12*0.88}{259}} = 0.1596[/tex]
So 8.04% to 15.96%
