Answer 1

I have solved incorrect part i.e. part b.

It should be

The provided sample mean is à = 134.8 and the sample standard deviation is s = 1.7889. The size of the sample is n = 5 and the required confidence level is 95%. The number of degrees of freedom are df = 5 – 1 = 4, and the significance level is a = 0.05. Based on the provided information, the critical t-value for a = 0.05 and df = 4 degrees of freedom is tc = 2.776. The 95% confidence for the population mean ji is computed using the following expression CI-*-***+ te xs vn Therefore, based on the information provided, the 95% confidence for the population mean μis CI = ( 134.8 = (13418 2.776 x 1.7889 15 134.8 + 2.776 x 1.7889 75 2 = (134.8 – 2.221, 134.8 + 2.221) = (132.579, 137.021)



134.8 - 2.776 1.7889 V5 1.7889 to 134.8 +2.776- 5
