In planning the operation of a new school, one schoolboard member claims that four out of five newly hiredteachers will stay with the school for more than a year,while another school board member claims that it wouldbe correct to say three out of five. In the past, the twoboard members have been about equally reliable in theirpredictions, so in the absence of any other informationwe would assign their judgments equal weight. If oneor the other has to be right, what probabilities wouldwe assign to their claims if it were found that 11 of 12newly hired teachers stayed with the school for more thana year?

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 60.92. You want to test this claim.The null and alternative hypothesis in symbols would be: a) H0:p≤60.92H1:p > 60.92 b) H0:μ=60.92; H1:μ≠60.92 c) H0:μ ≥ 60.92; H1:μ < 60.92 d) H0:μ ≤ 60.92; H1:μ > 60.92 e) H0:p≥60.92; H1:p<60.92 f) H0:p=60.92; H1:p≠60.92 The null hypothesis in words would be: The average price of all textbooks from the store is $$ 60.92 The average price of textbooks in a sample is $$ 60.92 The average of price of all textbooks from the store is less than $$ 60.92. The proportion of all textbooks from the store that are less than 60.92 is equal to 50% The average of price of all textbooks from the store is greater than $$ 60.92. Based on a sample of 110 textbooks at the store, you find an average of 65.72 and a standard deviation of 17.The point estimate is: ______ (to 3 decimals)The 95 % confidence interval (use z*) is: _____ to ______…
