Question

Use the normal approximation to find the indicated probability. the sample size is n, the population proportion of successes is p, and x is the number of successes in the sample. n = 86, p = 0.68: p(54 x 61) 9)

Answer 1

To find the indicated propability we will use the normal approximization. The sample size is;n= 86, The population proportion of successes is;p= 0.68: and the number of successes in the sample is x
P(54 ≤ X≤ 61)
0.6330 is the answer in this question which is the probability.
