Step-by-step explanation:
After working this way for 6 months he takes a simple random sample of 15 days. He records how long he walked that day (in hours) as recorded by his fitness watch as well as his billable hours for that day as recorded by a work app on his computer.
Slope is -0.245
Sample size n = 15
Standard error is 0.205
Confidence level 95
Sognificance level is (100 - 95)% = 0.05
Degree 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

Hope this helps!
We are given to understand as per the problem that one must save 10% of their take home pay.
Reggie's take home pay is $2,340 per month
As per the rule Reggie must save 10% of 2,340 per month = 0.10*2,340 = $234 per month
Since we need to know the savings in a year, we have to multiply the monthly savings by 12 since there are 12 months a year
Minimum amount per year that he should save = $234 *12 = $2,808
Minimum amount per year that he should save = $2,808
