It’s also a good business practice to check the company’s work quality before we proceed in getting their service. It can even be said that requesting for free samples from an online printer may save time and expenses for business.

Can someone help me with this question about random samples and standard deviation?

Here is a link to the question:
http://farm3.static.flickr.com/2021/2260865217_587efbd43c_o.jpg

The formula for test statistic is (xbar - μ) / sample standard deviation

Plug in 190 for xbar, 200 for μ, and 47 for sample standard deviation.

(190-200)/47 = -0.213

And your level of significance is 0.03. The z-score associated with p=0.03 is about -1.9. That means for this level of significance, to reject your null hypothesis based on the sample, the sample would have to produce a test statistic at least as extreme as -1.9 (in other words, less than or equal to -1.9). -0.213 isn't even close to that small, so you can't reject the null hypothesis.

The correct answer is F. You cannot reject the null because z is not less than -1.9.
