Question
Please do this on MS EXCEL. Please show the step by step process on EXCEL. So I can use it as a guide. Thank you.
Question:
(a) If the and s are unchanged, but there are 10 measurements (N=10) instead of 5, what would be the confidence interval?
(b) How does increasing the number of replicate measurements affect the reliability of measurements? Explain your answer. (Hint: better precision gives smaller confidence intervals)
(c) Based on the data given, which of these can be considered an outlier? Prove it (Use Grubb's Test)

Transcribed Image Text:A. In replicate analyses, the carbohydrate content of a glycoprotein ( a protein with sugars attached to it) is found

- Heights for teenage boys and girls were calculated. The mean height for the sample of 50 boys was 167 cm and the variance was 57. For the sample of 56 girls, the mean was 153 cm and the variance was 67. There is no reason to assume the variances would be equal. Estimate how much taller teenage boys are using a 99% confidence level. Express this in the (point estimate) ± (margin of error) format. Round answers to 2 decimal places.

- Import the data from the Hill City Excel file into Minitab.You are trying to predict Price.Note: Mtn View=1 if there is a mountain view, 0 otherwise. The rest of the variables should be self explanatory. 1.Perform an F Test for overall significance of the model 2.Perform a T test for slope for the age variable 3. Find a 95% confidence interval for the slope of the SqFeet variable4. Create a prediction, CI, and PI for 1 new set of x values (any valid numbers you want), and interpret each.5. Run the residual plots and indicate if they show any problems with the model.arrow_forwardStep 2 (b) Which of the two intervals conveys more precise information about the value of the population proportion? Recall that a smaller standard error of results in a narrower confidence interval. A narrower confidence interval is then more precise. The width of Interval 1, (0.27, 0.35), is 0.35 0.27 = and the width of Interval 2, (0.30, 0.34), is 0.34 -0.30 = Submit Skip (you cannot come back) Therefore, --Select--- is the narrower and more precise interval.arrow_forwardPlease answer the question in the picture below to answer the question in the other picturearrow_forward
