lesya692 [45]

Answer:

Step-by-step explanation:

Given that a marketing research firm is estimating which of two sodas (A or B) college students prefer.

Sample size of 75 was taken at random.

Since sample size is sufficiently large i.e. >30, and also since samples are taken at random, we can assume that sample proportion

p= \frac{45}{75} =0.6 follows a normal distribution with mean = 0.6 and variance = npq = 75(0.6)(0.4)

Yes, this sample is large enough to calculate a confidence interval.

           527.8=6.28(6)h+(6.28)(6²)

           527.8=37.68h+(6.28)(36)

           527.8=37.68h+226.08

        -226.08              -226.08

          301.72=37.68h

301.72/37.68=37.68h/37.68
