Please answer the following questions: 1. What is the resolution of calipers? 57.5 2. What is degree of freedom of the measurement? dof=15-1=M 3. Calculate the 95% confidence interval for the true mean (1). Please show all your work. 1-a=0.95 => a = 0.05 to os = 1.7613 considence interval= it taos server = 28.313 + 1,76134 0.398 VIS =) 658.132, 58.999) 4. Calculate the experimental t-statistic. Please show all your work. T 58.313 - 567.450mm Sw 0.398 N vis
5. Using hypothesis testing, determine whether the sample mean is not equal to the block population's true mean (W+x) with a confidence level of 95%. Please clearly indicate your choice of the null and alternate hypotheses, and show all your work. 6. Get the sample mean and standard deviation from another group. Using hypothesis testing, determine if there is a significant difference between the block widths of the two groups at a confidence level 95% using the t-test comparison.
