Here, n=28 and confidence level is 0.98. The level of significance is 0.02. The degrees of freedom is 27 (=n1). Using Excel formula =T.INV(1(0.022),27). the critical value that corresponds to a confidence level of 98% is 2.473 (rounded to three decimals). ta2=2.473.

According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal.f(x)= where X.μ=σ=. Find the probability that the individual lost more than 8 pounds in a month.Suppose it is known that the individual lost more than 9 pounds in a month. Find the probability that he lost less than 13 pounds in the month.
