Answer:

To calculate the standard deviation of the distribution, we first need to find the expected value of X, which is the average number of girls in the 8 possible outcomes.

Since each child can be either a boy or a girl with equal probability, there are 2^3 = 8 possible outcomes for the number of boys and girls. We can list these outcomes and the corresponding number of girls:

BBB (0 girls)

BBG (1 girl)

BGB (1 girl)

BGG (2 girls)

GBB (1 girl)

GBG (2 girls)

GGB (2 girls)

GGG (3 girls)

To find the expected value of X, we add up the number of girls in each outcome and divide by the total number of outcomes:

E(X) = (0 + 1 + 1 + 2 + 1 + 2 + 2 + 3) / 8 = 1.5

Next, we need to calculate the variance of X. The variance is the expected value of the squared deviation from the mean:

Var(X) = E[(X - E(X))^2]

We can calculate this by finding the squared deviation from the mean for each possible outcome, multiplying by the probability of that outcome, and summing over all outcomes:

Var(X) = [(0 - 1.5)^2 / 8 + (1 - 1.5)^2 / 4 + (2 - 1.5)^2 / 4 + (3 - 1.5)^2 / 8]

= 0.65625

Finally, the standard deviation is the square root of the variance:

SD(X) = sqrt(Var(X)) = sqrt(0.65625) = 0.81 (rounded to two decimal places)

Interpretation: The standard deviation of the distribution of the number of girls in a family of three children is 0.81. This means that on average, the number of girls in such families is 1.5, but the actual number of girls can vary by up to 0.81 from this average.

In a command economy, the onus of producing goods and services to meet the needs of the society falls upon government agencies.  (Option A)

It is an economic system wherein the government exercises control over the means of production and dictates what goods and services will be produced and in what quantities.

Private businesses, if present, operate under strict governmental regulations concerning specific areas and goods production.

The involvement of family members and international corporations in such economies is usually absent as centralized control by the government overpowers any other entity.

Thus, the correct answer is: Option A)

Answer:

A. A cliffhanger

Explanation:

A cliffhanger is a way to grab audience members' attention by starting a dramatic or exciting story and not finishing it until later in the speech or presentation. This technique is commonly used in storytelling and in speeches to keep the audience engaged and interested. By withholding the conclusion or resolution of a story or anecdote, the speaker creates a sense of suspense and anticipation in the audience, making them more likely to pay attention and stay engaged. A cliffhanger can be a powerful tool for holding the attention of an audience and building excitement and interest in a speech or presentation.

a)The test statistic is 0.35

b) The P-value is 0.3632

c) There is not sufficient evidence to reject the null hypothesis that p = 0.5

Given data

Sample size, n =130

Population proportion, p= 0.5

Significance level, = 0.05

Number of success , x= 67

Sample proportion, = 67/130

= 0 5154

The test statistic will be:

= 0.5154 - 0.5 / ✓0.5(1 - 0.5) / 130

Answer:

The answer is C

Explanation:

The answer is C. You should try to leave emotions out of financial decisions. While emotions can certainly impact financial decisions, it is important to try to make decisions based on rational, objective factors whenever possible. Allowing emotions to drive financial decisions can lead to impulsive choices that may not be in one's best interest in the long term. That being said, it can be difficult to entirely separate emotions from financial decisions, as money and personal values are often closely intertwined.

The distribution of x, the speed for a randomly selected car  can be expressed as a normal distribution with a mean of 78 MPH. Thus, we can write it as X ~ N(78, 10 )

The Gaussian distribution, also known as normal distribution, is often employed in statistical analysis due to its symmetrical bell-shaped curve for the continuous probability distribution.

Thus, it is correct to state that the distribution of x, the speed for a randomly selected car  can be expressed as a normal distribution with a mean of 78 MPH and standard deviation 10 MPH , since these are the parameters of the underlying distribution. More formally, we can write:

X ~ N(78, 10)

Answer: $7.50

Explanation:

first find the cost without the 3 dollars off. this would be 42 + 3 = $45

Next, divide this cost by 6 to find the price per ticket, so 45/6 = 7.5

So each ticket was $7.50

To find the probability of mayonnaise and mustard, we can use the formula:

P(mayonnaise and mustard) = P(mayonnaise) + P(mustard) - P(mayonnaise or mustard)

Plugging in the given values, we get:

P(mayonnaise and mustard) = 0.64 + 0.59 - 0.89

P(mayonnaise and mustard) = 0.34

Therefore, the probability of a customer ordering both mayonnaise and mustard is 0.34.

Preference is a greater liking for one alternative over another or others. Fatima prefers ketchup to mustard. Therefore, she likes ketchup more than she likes mustard. Fatima prefers mayonnaise to relish.

She likes mayonnaise more than she likes relish. However, Fatima is indifferent between mustard and relish. Therefore, she has no preference between these two.

Therefore, the probability of a customer ordering both mayonnaise and mustard is 0.34.
