Using The Chi-Square Distribution Table, find the values for  χ2left  and χ2right  of the following.     (b) When  =α0.20  and  =n23 ,   χ2left =     χ2right =

Find the indicated IQ score. The graph to the right depicts IQ scores of​ adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.                   x 0.2525         A symmetric bell-shaped curve is plotted over a horizontal scale. A vertical line runs from the scale to the curve at labeled coordinate x, which is to the right of the curve’s center and peak. The area under the curve to the right of the vertical line is shaded and labeled 0.2525.       Question content area bottom Part 1 The indicated IQ score is enter your response here. ​(Round to the nearest whole number as​ needed.)

Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 120 pounds and a standard deviation of 39.9 pounds. Random samples of size 18 are drawn from this population and the mean of each sample is determined. H = o: = (Round to three decimal places as needed.) Sketch a graph of the sampling distribution. Choose the correct graph below. OA. O B. Oc. OD. -110.6 9.4 129.4 101.2 120 138.8 -350.6 9.4 369.4 91.8 120 148.2 Click to select your answer(s). P Type here to search 11:24 AM 2/1/2021 Home End

Please explain:Use your calculator to calculate the following. (P(X > 7), X has an F-distribution with 5 numerator df and 10 denominator df. P(3 < X < 15), X has an F-distribution with 5 numerator df and 10 denominator df.
