question 1: What is the critical value for an upper‐tailed hypothesis test of the population mean when the population variance is unknown in which a null hypothesis is tested at the 0.01 level of significance based on a sample size of 22? Options 2.518 1.721 1.734 1.323 Question 2: The state lottery office claims that the average household income of those people playing the lottery is at least $37,000. Assume that the distribution of household income of those people playing the lottery is normally distributed with a standard deviation of $5,000. Suppose that for a sample of 16 households, it is found that the average income was $35,000. What is the test statistic for this test?
