The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, s^{2} = 1296

Standard deviation, s = √1296

                                   = 36

Standard error, SE = \frac{s}{\sqrt{n} }

                              = \frac{36}{\sqrt{36} }

                              = \frac{36}{6}

                              = 6

Concept

  • Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
  • Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by 's^{2}'
  • Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

we believe that 42% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to
Maksim231197 [3]

Answer:

A sample of 1077 is required.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is of:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

42% of freshmen do not visit their counselors regularly.

This means that \pi = 0.42

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.327.

How large of a sample size is required?

A sample size of n is required, and n is found when M = 0.035. So

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.035 = 2.327\sqrt{\frac{0.42*0.58}{n}}

0.035\sqrt{n} = 2.327\sqrt{0.42*0.58}

\sqrt{n} = \frac{2.327\sqrt{0.42*0.58}}{0.035}

(\sqrt{n})^2 = (\frac{2.327\sqrt{0.42*0.58}}{0.035})^2

n = 1076.8

Rounding up:

A sample of 1077 is required.

You earn $7.50 per hour at a fast food restaurant. You earned $123.75 last week. How many hours did you work last week?
ladessa [460]
I believe you would need to divide 123.75 by 7.50.

The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
