Answer: You are not comparing two things, and you're asking a question that can only be answered one way.

Step-by-step explanation: Statistical questions are comparing two things, or one alone. Therefore, Asking someone what grade are they in is not statistical because of how it is one student being compared, not anyone else.

A notebook costs $4.50 plus sales tax.after sales tax,the notebook is $4.86 what is the sales tax rate

Yakvenalex [24]

The sales tax rate would be 8%.

To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.

4.86 - 4.50 = 0.36

So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total.

0.36 ÷ 4.50 = 0.08

This means that the sales tax is 8%.

Hope I could help!

A random sample of the closing stock prices in dollars for a company in a recent year is listed below. Assume that sigma is $2.

garik1379 [7]

Answer:

[ 17.8941, 19.6621]

Step-by-step explanation:

Given:

widths :

18.41 19.11 18.67 18.97 21.97 17.26 18.69 16.73 21.97 16.43 21.97 21.66 18.77 17.93 15.47 16.44

Total number of observations = 16

Mean of the sample = $\frac{\textup{Sum of observations}}{\textup{Total number of observations}}$

= $\frac{\textup{300.45}}{\textup{16}}$

= 18.7781

For 90% confidence level, z value = 1.645

Therefore,

Margin of error, E = $z\frac{\sigma}{\sqrt n}$

= $1.645\times\frac{2.15}{\sqrt{16}}$

= 0.884

thus,

Confidence interval = Mean ± E

Confidence interval = [18.7781 - 0.884 , 18.7781 + 0.884 ]

= [ 17.8941, 19.6621]
