Clarissa is not correct. If she were to choose one from the stack at random, it means that she has a 25%, or a 1/4 chance to pick the oatmeal, just like the other breakfast items.

If there were to be more oatmeals than any of the other items, it will heighten the chance of her getting oatmeal which would be the only way to make her statement correct.

A public health department wants to determine the rate that parents of teen boys are choosing to vaccinate their sons for HPV wi

viktelen [127]

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The sample size is $n = 64$

The proportion that choose to vaccinate the teen boys is $\r p = 0.12$

considering the first statement

The 95% confidence interval is 12% ± the margin of error*standard deviation is false because

The 95% confidence interval is is %12 ± the margin of error

considering the second statement

The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem

np = 64 * 0.12 = 7.68

and this value is less than 10 hence the confidence interval should not be calculated

considering the third statement

A 99% confidence interval will be smaller than the 90% confidence interval is false

This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
