Question 1 of 8

Calculator allowed

A two-sided 94% mean-confidence procedure uses iid normal observations with known positive population SD. Its unrounded intervals therefore have exact coverage 47/50. Repeat the procedure with 111 fresh independent samples from the same population. Find the expected numbers of intervals containing and missing the fixed population mean. Give exact values; an expectation need not be an integer
