In each part, give the value of the standardized statistic (z-score) for the sample mean. 100, σ = 8, n = 4 (a) x = 88, μ = Z = (b) x = 88, μ = 100, σ = 8, n = 64 Z = (c) x = 10.63, μ = 10.0, σ = 7, n = 10,000 z =

The test scores of 16 students are listed below:             44, 46, 51, 57, 60, 63, 65, 70, 75, 76, 85, 87, 90, 94, 95, 97.            (a) Find the median of the above data

Calculate the 75% percentiles, 25% percentiles, and the IQR for the following data:   9, 12, 20, 5, 14, 7, 16, 13   IQR = Q3 – Q1

Describe when you would use an analysis of variance versus an independent samples t-test.

Find the (a) mean, (b) median, (c) mode, (d) midrange, (e) range, (f) variance, and (g) standard deviation. Please label your answers with a-g. The data that is shown below states the number of cookies each student ate at the bake sale. 1,1,2,3,5,3,5,7,3,3 Upload

calculate the 30th percentile of the data shown, 3.4,3.9,7,11.7,14,20.3,26.2,27.8,28.9

If a data set has 15 mean standard daviation 2 , percentage observation lie between 13 and 17

The data table shows the ages in years of 10 men with systolic blood pressure.  The Age,x: 18, 26, 39, 46, 48, 64, 68, 31, 58, 22. and systolic blood pressure, y: 111, 123, 145, 130, 201, 183, 198, 131, 177, 119. The sample correlation coefficient r is 0.881. Remove the data entry for the man who is 48 years old and has a systolic blood pressure of 201 millimeters of mercury from the data set and find the new correlation coefficient.

The ages in years of a random sample of shoppers at a gamming store are shown. 12, 17, 23, 13, 20, 16, 20, 18, 13, 18. Find the range, mean, variance and standard deviation.

The data table shows the ages in years of 10 men with systolic blood pressure.  The Age,x: 18, 24, 39, 45, 49, 63, 71, 29, 57, 22 and systolic blood pressure, y: 109, 121, 142, 133, 199, 186, 199, 132, 177, 117. The sample correlation coefficient r is 0.913. Remove the data entry for the man who is 49 years old and has a systolic blood pressure of 199 millimeters of mercury from the data set and find the new correlation coefficient.
