- 2. A city had an unemployment rate of 7%. The mayor pledged to lower this figure and supported programs to decrease unemployment. A group of citizens wanted to test with 0.032 label of significance if the unemployment rate had actually decreased, so they obtained a random sample of 500 citizens to see what proportion of the sample was unemployed. Only 32 citizens in the above sample is still unemployed. What is the probability of Type II error if the actual unemployment rate is 6.5% please don't use software everything needs to be done by hand. Explain because I don't understand my professor.

Which of the following is true about standard deviation? The first step in calculating the standard deviation is calculating the square root. The second step in calculating the standard deviation is to subtract each measurement from the intermediate value and then square that difference. The last step in calculating the standard deviation is to sum the squared values and divide by the number of values minus one. Standard deviation is a type of average where the positive and negative numbers sum to zero. The amount of difference of the measurements from the central value is called the sample standard deviation.arrow_forward
