Answer:
The answer is
Step-by-step explanation:
After operating under these conditions for a period of 6 months, he selects a simple random sample of 15 days. He logs the hours he walked each day as tracked by his fitness monitor, alongside his recorded billable hours from a work application on his computer.
The calculated slope is -0.245
The number of samples is n = 15
The standard error is 0.205
The confidence level is 95
The significance level is (100 - 95)% = 0.05
The degrees of freedom is n - 2 = 15 - 2 = 13
Critical Value = 2.16 = [using excel = TINV (0.05, 13)]
Marginal Error = Critical Value * standard error
= 2.16 * 0.205
= 0.4428
