statistical evidence that the tutoring is effective in improving scores? Use a significance level of 0.05. We have the differences (gain orloss), but we still need to compute the mean, standard deviation, and know the sample size for the differences (use Excel or Sheets forthis computation). Once those are found, we can apply methods that are used for a 1 sample t-test.StudentBefore Tutoring After TutoringDifference7175667913367704778587585106.76859.7883889956.9.62822010568024Null Hypothesis, HOAlternative Hypothesis, H1Test Statistic, tP-valueSignificance levelConclusion3.2.

Thanks for your help, everything is in the screenshot. Data as well here is text just in case. 216294191199300301256287294202202
attached - see image - question was previously not completed. I just got the answer for range - there are multiple questions within the problem - thanks
The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude?

A process that manufactures glass sheets is supposed to be calibrated so that the mean thickness μ of the sheets is more than 4 mm. The standard deviation of the sheet thicknesses is known to be well approximated by σ = 0.23 mm. Thicknesses of each sheet in a sample of sheets will be measured, and a test of the hypothesis H0 : μ ≤ 4 versus H1 : μ > 4 will be performed. Assume that, in fact, the true mean thickness is 4.04 mm. Section 06.07 Exercise 06.a a) If 100 sheets are sampled, what is the power of a test made at the 5% level? The power of a test made at the 5% level is _____. b) How many sheets must be sampled so that a 5% level test has power 0.95? ______ sheets must be sampled so that a 5% level test has power 0.95.c) If 100 sheets are sampled, at what level must the test be made so that the power is 0.90? The test must be made at _____% level so that the power is 0.90. d) If 100 sheets are sampled and the rejection region is X¯ ≥ 4.02, what is the power of the test?…
