5.3. 14-T Assigned Media Question Help A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this tumor occurred in a certain town, which had 18,280 children. a. Assuming that this tumor occurs as usual, find the mean number of cases in groups of 18,280 children. b. Using the unrounded mean from part (a), find the probability that the number of tumor cases in a group of 18,280 children is 0 or 1. c. What is the probability of more than one case? d. Does the cluster of four cases appear to be attributable to random chance? Why or why not? a. The mean number of cases is 0.201 (Type an integer or decimal rounded to three decimal places as needed.) b. The probability that the number of cases is exactly 0 or 1 is (Round to three decimal places as needed.)X 10.2.7 Assigned Media Question Help Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 136 to 189 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x = 167.60 cm, y = 81.60 kg, r=0.396, P-value = 0.000, and y = - 107 + 1.08x. Find the best predicted value of y (weight) given an adult male who is 180 cm tall. Use a 0.01 significance level. The best predicted value of y for an adult male who is 180 cm tall is |kg. (Round to two decimal places as needed.)10.2.21-T Assigned Media Question Help Find the regression equation, letting the first variable be the predictor (x) variable. Using the listed actress/actor ages in various years, find the best predicted age of the Best Actor winner given that the age of the Best Actress winner that year is 58 years. Is the result within 5 years of the actual Best Actor winner, whose age was 43 years?
