The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving th

USPshnik [31]

Answer:

C) There is not sufficient evidence to support the claim that the mean attendance is greater than 523.

Step-by-step explanation:

Let μ be the the average attendance at games of the football team

The claim: the average attendance at games is over 523

Null and alternative hypotheses are:

$H_{0}$ : μ=523

$H_{a}$ : μ>523

The conclusion is failure to reject the null hypothesis.

This means that test statistic is lower than critical value. Therefore it is not significant, there is no significant evidence to accept the alternative hypothesis.

That is no significant evidence that the average attendance at games of the football team is greater than 523.

Keelahs clothing store buys coats for $50 and then sells them for $80 what is the percent of mark up on the price of the coat sh

olchik [2.2K]

I don't know if you meant profit or markup but,

What percent of 50 is 30? It's 3/5 or 60%. So there is a 60% markup on the original price of 50$.
