Answer:

18.67% probability that the sample proportion does not exceed 0.1

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

For the sampling distribution of a sample proportion, we have that \mu = p, \sigma = \sqrt{\frac{p(1-p)}{n}}

In this problem, we have that:

\mu = 0.14, \sigma = \sqrt{\frac{0.14*0.86}{59}} = 0.045

What is the probability that the sample proportion does not exceed 0.1

This is the pvalue of Z when X = 0.1. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{0.1 - 0.14}{0.045}

Z = -0.89

Z = -0.89 has a pvalue of 0.1867

18.67% probability that the sample proportion does not exceed 0.1
