Question: Question 1) Which are important conditions one should check to ensure that the sampling distribution of x is nearly normal and the estimate of Standard

Question 1) Which are important conditions one should check to ensure that the sampling distribution of x is nearly normal and the estimate of Standard Error safe to use in the context of a z-test: (you can pick more than one)

A. Sample size consists of less than 10% of the population and observations were randomly sampled B. Sample size is large (n30) C. Population distribution is not strongly skewed

Question 2) Test scores for 12th graders in New York Public Schools are normally distributed. The average score on the test is 26 with a standard deviation of 4. Use the 68-95-99.7 rule to estimate the probability of a 12th grader in New York Public Schools scoring more than 34. (please show the work)

Question 3) When the p-value associated with your hypothesis test is>alpha, it is best to say:

A. We have found enough evidence to reject the null hypothesis and as such, we favor the alternative hypothesis.

B. We have found evidence for both our null and alternative hypothesis.

C. We did not find evidence to support the alternative hypothesis, so we accept the null hypothesis.

D. We have failed to find evidence to reject the null hypothesis.

Question 4) A teacher is gathering data on computer usage of other college students. A description of the variables are presented below: computer (1 = Macintosh, 2 = PC) laptop (1 = laptop, 2 = desktop) daysUse (number of days per week the student uses the computer) moneySpent (the amount of money the student spent on their computer)

Which of the variables are quantitative and discrete? (please give reasoning)

Question 5) Please estimate the mean and median for below histogram and give calculations.
