Question

"Thanks to the new and improved treatment, the average resting heart rate of these patients will rise above 120 beats per minute."

a) Identify the confidence coefficient associated with this hypothesis test if the claim is to be tested using 90% confidence.

The sample data is as follows:

Sample size = 25

Sample mean = 106

Sample standard deviation = 5.2

Note: If this is a two-sided test, you can enter the positive or the negative value. Confidence coefficients use 3 decimals.

b)

Identify the confidence coefficient associated with this hypothesis test if the claim is to be tested using 90% confidence.

The sample data is as follows:

Sample size = 20

Sample mean = 110

Sample standard deviation = 1.9

Note: If this is a two-sided test, you can enter the positive or the negative value. Confidence coefficients use 3 decimals.
