Answer: C. There is sufficient evidence to support the claim . $\mu>140$

Step-by-step explanation:

Given (claim) :The mean monthly gasoline bill for one household is greater than $140.

Let $\mu$ be the population mean.

Then, the set of hypothesis for this claim will be:-

$H_0:\mu\leq140\\\\ H_a:\mu>140$

kondor19780726 [428]

Let x = number of students in each of the remaining rows

266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
