The average salary for a civil engineering major is $75,000 with a standard deviation of $10,000. A university wants to determine how well their students in their civil engineering program get paid after graduating. They ask one class of 30 students in a course to give their salaries after graduating. What is the probability the average salary of the 30 students is between $73,000 and $77,000 O The sample size of 30 students is too small to use the Central Limit Theorem, the university needs to find a larger class O 0.73 O 0.16 O 0.68

Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $247 with a standard deviation of $63. Random samples of size 33 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is
Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following.

Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability. In a sample of 900 gas stations, the mean price for regular gasoline at the pump was $2.831 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 55 is drawn from this population. What is the probability that the mean price per gallon is less than $2.829?
Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has noeffect, so the probability of a girl is 0.5. Assume that the groups consist of 32 couples. Complete parts (a) through (c) below. Find the mean and the standard deviation for the numbers of girls in groups of 32 births.

She randomly selected a sample of 24 and 21 married women from Village A and Village B, respectively. The following data are the mean and standard deviation for each group: Village A: x = 18.63 and s = 5.54 Village B: x = 24.90 and s = 5.54 Test the hypothesis that the women in Village A get married younger than women in Village B.
