The answer is step 3. Step 2 is suppose to be 3 x 7 and the answer is 21 but he writes 7 in step 4
<em><u>The equation for the product of -2 and -30 gives 60 is:</u></em>

<em><u>Solution:</u></em>
Given that, The product of -2 and -30 gives 60
We have to write the sentence as equation
It includes operations such as addition, subtraction, multiplication and division.
From given statement,
The product of -2 and -30 gives 60
Here, "product" means multiplication
Therefore, -2 multiplied with -30 gives 60
Which is written as equation as,

Thus the given sentence is translated into equation

Answer: fail to reject the seven-minute average waiting time claim.
Step-by-step explanation:
As per given ,
Objective for test : the average waiting time is seven minutes or more.
Then ,
Since alternative hypothesis is right-tailed thus the test is an right-tailed test.
In a right tailed test , the rejection area lies on the right side of the critical value.
It means that if the observed z-value is greater than the critical value then it will fall into the rejection region other wise not.
i.e. If the value of your test statistic is less than the critical value, the correct decision is we fail to reject null hypothesis.
i.e. fail to reject the seven-minute average waiting time claim.
The complete statement would become:
If the value of your test statistic is less than the critical value, the correct decision is to fail to reject the seven-minute average waiting time claim.
