Answer:

T = 2w + 37

Step-by-step explanation:

Let T represent the total amount of videos Rachel has after w weeks

Rachel already owns 37 videos

She purchases 2 more each week

Therefore, after w weeks, the total amount of videos Rachel has can be represented by the expression:

2w + 37

Then the total after w weeks can be modeled by the equation:

T = 2w + 37

You need to compute the a 90% confidence interval for the population mean. How large a sample should you draw to ensure that the
RSB [31]

Answer:

The sample size required is 102.

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for population mean <em>μ</em> is:

CI=\bar x\pm z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}

The margin of error for this interval is:

MOE= z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}

Given:

<em>σ</em> = 9.2

(1 - <em>α</em>)% = 90%

MOE = 1.5

The critical value of <em>z</em> for 90% confidence level is:

z_{0.10/2}=1.645

*Use a <em>z</em>-table.

Compute the value of <em>n</em> as follows:

MOE= z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}

      n=[\frac{z_{\alpha/2}\times \sigma}{MOE}]^{2}

         =[\frac{1.645\times 9.2}{1.5}]^{2}\\=101.795\\\approx102

Thus, the sample size required is 102.
