Answer:
(Rows, chairs)= (2,15), (3,10), (5,6)
Step-by-step explanation:
Given: There are 30 chairs in the band room.
Criteria: There has to be same number of chairs in each row. There must be more than one row and the number of chairs in each row must also be greater than the number of rows.
First finding the divisor of 30:
1,2,3,5,6,10,15,30
Now, we need to look into divisor which qualify the criteria in the multiple of rows and number of chairs.
∴ 30=
30=
30=
∴ Mr Avery can use either of these option to arrange rows and chairs.
(Rows, chairs)= (2,15), (3,10), (5,6)

Answer:
The significance level is and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:
So we reject the null hypothesis is
Step-by-step explanation:
For this case we define the random variable X as the number of entry-level swimmers and we are interested about the true population mean for this variable . On specific we want to test this:
Null hypothesis:
Alternative hypothesis:
And the statistic is given by:
