Please help me with The mean and The Deviation for question 5.1.21. The rest of the questions are listed in the pictures, note that question for the picture 10. 1. 15T is all the way in the bottom of the second picture and that is only question I need help with from the question 10. 1. 15T The rest has been answered. Most of the questions has being answered I just need help with the ones that are empty.

10.1. 15-T Assigned Media Question Help Listed below are amounts of court income and salaries paid to the town justices. All amounts are in thousands of dollars. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using a= 0.05. Is there sufficient evidence to conclude that there is a linear correlation between court incomes and justice salaries? Based on the results, does it appear that justices might profit by levying larger fines?

Assume that the offspring peas are randomly selected in groups of 10. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 10. The value of the mean is u = 7.5 peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is o = 1.4 peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of peas or fewer are significantly low. (Round to one decimal place as needed.)
