A superintendent of a school district conducted a survey to find out the level of job satisfaction among teachers. Out of 53 tea
frez [133]

Answer:

b. 1.15

Step-by-step explanation:

The z statistics is given by:

Z = \frac{X - p}{s}

In which X is the found proportion, p is the expected proportion, and s, which is the standard error is s = \sqrt{\frac{p(1-p)}{n}}

Out of 53 teachers who replied to the survey, 13 claim they are satisfied with their job.

This means that X = \frac{13}{53} = 0.2453

She find that the proportion of satisfied teachers nationally is 18.4%.

This means that p = 0.184

Standard error:

p = 0.184, n = 53.

So

s = \sqrt{\frac{0.184*0.816}{53}} = 0.0532

Z-statistic:

Z = \frac{X - p}{s}

Z = \frac{0.2453 - 0.184}{0.0532}

Z = 1.15

The correct answer is:

b. 1.15
