Alaska's Katmai National Park celebrates fat bear week every year in the beginning of October, when brown bears are getting ready to go into hibernation. During the fat bear week, the public votes on bears to advance in the bracket through single-elimination rounds. Adult male bears regularly weigh around and even over 1000 pounds for their peak fall weights, while adult female bears generally weigh 1/3 less than the males. Suppose the weights of all ready-to-hibernate brown bears in the national park are distributed as shown in the following histogram. Weights of Bears 10 200 400 600 800 1000 1200 Weight in pounds The mean of all the peak fall bear weights is 695 pounds, and the standard deviation is 279 pounds, For a random sample of 30 bears, what is the probability of obtaining a sample mean less than 720 pounds? If the conditions to perform the necessary calculation are not satisfied, enter -1" instead. Give your answer accurate to four digits beyond the decimal point. Answer.…

Emily is trying to check if the nutritional content of different formulas have different effects on mice. She uses five mice to test each type of formulas (A, B, and C) and Formula A is simply a placebo. Each mouse's weight is recorded in grams. At the end of a specified time period, each mouse is weighed again and the net gain in grams is recorded as shown in Table 1 below. Formula Formula Formula A В 40 47 51 32 38 41 42 49 38 36 46 46 39 44 49 Using an F-test, determine whether or not the variance in weight gain is statistically the same among the mice that were using Formula B and Formula C. Test at a confidence level of 90%. (HINT: Remember that the bigger standard deviation goes in the numerator when calculating the test statistic) a. Should we run the test on all three columns or only on two columns? (Write "2" or "3" in the blank): b. The F-test statistic calculated for this problem is (Round to three decimal places). c.

An agricultural field trial compares the yield of two varieties of corn. The researchers divide in half each of 8 fields of land in different locations and plant each corn variety in one half of each plot. After harvest, the yields are compared in bushels per acre at each location. The 8 differences (Variety A - Variety B) give x¯=3.07 and s=5.11. Does this sample provide evidence that Variety A had a higher yield than Variety B? (a) State the null and alternative hypotheses: (Type "mu" for the symbol μμ , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1)H0 : Ha : (b) Find the test statistic, t = 7,6
