Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 133 to 194 cm and weights of 38 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x = 167.59 cm, y = 81.48 kg, r=0.117, P-value = 0.246, and y = - 109 + 1.18x. Find the best predicted value of y (weight) given an adult male who is 146 cm tall. Use a 0.01 significance level. The best predicted value of y for an adult male who is 146 cm tall is kg. (Round to two decimal places as needed.)Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by.r applying the 5% guideline for cumbersome calculations}. If it is not binomial and cannot be treated as binomial. identifyr at least one requirement that is not satised. Randomly selecting 15E] citizens of a state and recording their nationalities Choose the correct answer below. C} A. It is binomial or can be treated as binomial. C} E. It is not binomial because there are more than two possible outcomes. Cl C. It is not binomial because there are more than two possible outcomes and the trials are not independent. C} D. It is not binomial because the probability of success does not remain the same in all trials. A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.26 lb, the mean of all of the weights is x = 1.901 lb, and the standard deviation of the weights is s = 2.111 lb. a. What is the difference between the weight of 5.26 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.26 lb to a z score. d. If we consider weights that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the weight of 5.26 lb significant? a. The difference is Ib. (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z = (Round to two decimal places as needed.) d. The highest weight is
