x= number of students  x.     P(x) 0.    O.15 1.     0.35 2.     0.30 3.     0.15 4.     0.05   What is the maximum usual value of the number of students with "mathitis"? Would 3 students among 4 randomly selected be considered significantly high?

Need help with this question. Thank you :)

9. The average weight of a Coastal male Grizzly Bear is approximately normal with E(x); =795 pounds and SD * (x) = 80 pounds. How likely is it to randomly select 64 Coastal male Grizzly Bears with a sample average weight of 810 pounds or more? Find the z-score for the problem above. Round the answer to the nearest ten-thousandth.

The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. (a) x = 5 wins E Click the icon to view the table of numbers of wins and earned run average. (b) x = 10 wins (c) x = 21 wins (d) x = 15 wins - X Wins and ERA The equation of the regression line is y = x + (Round to two decimal places as needed.)
