a) Please choose the suitable control charts to test whether or not the process is in control. b) A new sample results in the following slab weights: 81.0, 81.0, 80.8, 80.6, and 80.5. Judge whether or not the process is in control based on the data (including new sample data). c) Based on the data in part b), the specification for the concrete slabs is 78kg to 81kg, is √n the specification being met? Using the formulation = A₂R (n is sample size and A2 refers to tables in Week 8 slide) to estimate the standard deviation from average range.

B) For each sample, plot the data points on a scatter plot (by hand without drawing the line of best fit) and ensure to add the appropriate labels on the plot

Consider these sample​ data: x1=15​, x2=9​, x3=3​, x4=22.   a. Find n.        b. Compute ∑xi.      c.Determine x.       a.n=

Find each of the following, rounded to the nearest tenth, if necessary, for the given set of data:   63,  78,  81,  82 a) range:  b) mean:  c) median:  d) standard deviation:  e) draw a box and whisker plot (we will look at your work):

A study is run to estimate the mean total cholesterol level in children 2 to 6 years of age. A sample of 9 participants is selected and their total cholesterol levels are measured as follows.  180  220 240  196  175  183  195  140  200 What is the sample mean? A) 196 B) 200 C) 192.11 D) 180

The data below lists states poverty rate, gun deaths per 100,000 people, high school graduation rate and the unemployment rate. Use a 2x2 contingency table for questions 1-3. Use the median to divide each list into 2 groups. 1) Test for independence between poverty rate and gun deaths. 2) Test for independence between high school graduation rate and gun deaths. 3) Test for independence between unemployment and gun deaths. 4) Divide the data into 3 groups by gun deaths: 0-9, 9.1-12 and 12.1-20. Use ANOVA to test the claim that the average poverty rate is the same for the three groups. Be sure to write down the mean and standard deviation for each group. 0-9 9.1-12 12.1-20 n = x = s = n = x = s = n = x = s =

The distribution of hemoglobin in grams per deciliter of blood if approximately N(14,1) in women and approximately N(16,1) in men. Use software or Table B to find the answers. A) What percent of women have more hemoglobin than the men's mean hemoglobin? B) What percent of men have less hemoglobin than the women's mean hemoglobin? C) What percent of men have more hemoglobin than the women's mean hemoglobin?

Please Literal C, and with the answers a and b  why these answers give the correct result for a and b
