0 Question 8 v A random sample of 36 female professional soccer players found an average height of 66.1 inches, with a standard deviation of 2.5 inches. Build a 95% CI for the mean height of female professional soccer players. This will be a T-lnterval since 0' is not known. So we need to compute the Degrees of Freedom: (if. =n1 a.d.f. = To find the Margin of Error, E, we need to find the Critical Value, TC. To do this we use ian{C + (1- C}12,d.f.), where in this problem C = 0.95. Round to three decimals. as}: 3 Next we find the Margin of Error: E 2 TC - T. Round to one decimal. n c.E= Finally, we compute our Cl: IE E (J u 2f :3 + E d. (#64 Question 9 To build a 91% CI for the mean of a population, you take a random sample of 32 values and find 3 = 20. What is the Margin of Error, E? Round the Critical Value and your answer to three decimals
