Enable Editing Exercise 1: Solve each statistics formula for the indicated variable. Since parts (a) and (b) involve quotients, start by multiplying both sides of the equation by the denominator in order to get rid of fractions Use the z.score formula Z=x-u to find the data value, x, ifwe know that Z-36, a. 40 and 5. Show each step. Using the proportion formula p=n,find the sample size,n, ifwe know that =0.36 and the number of successes, x, is 59. Show each step. Round your answer to the nearest whole number. b. We are going to take the marein of error formula and solve it for the sample size, n

Explanation / Answer

a) Z = 3.6

or, (x - 40) / 5 = 3.6

or, x = 40 + 3.6 * 5

or, x = 58

b) p = 0.36

or, 59/n = 0.36

or, n = 163.89

or, n = 164
