Question
The 95 % confidence interval of the capacity of a new rubber bladder (in liters) is given below. Given: U = 7.31 (Units as given in problem) L = 5.43 (Units as given in problem) Its hypothesized capacity (in liters) is: C = 4.66 (Units as given in problem) Question: 1. Enter: (1) if the 2 sided confidence interval indicates that the capacity IS significantly different from the hypothesized capacity; (2) if the 2 sided confidence interval indicates that the capacity is NOT significantly different from the hypothesized value.Explanation / Answer
The 95 % confidence interval of the capacity of a new rubber bladder (in liters) is given below. Given: U = 7.31 (Units as given in problem) L = 5.43 (Units as given in problem) Its hypothesized capacity (in liters) is: C = 4.66 (Units as given in problem) Question:
1. Enter: (1) if the 2 sided confidence interval indicates that the capacity IS significantly different from the hypothesized capacity;
(2) if the 2 sided confidence interval indicates that the capacity is NOT significantly different from the hypothesized value.
95% CI=(5.43, 7.31) does not contain the hypothesized value 4.66.
The null hypothesis is rejected.
