Increasing numbers of businesses are offering child-care benefits for their workers. However, one union claims that fewer than 8
Y_Kistochka [10]

Answer: c. -2.15

Step-by-step explanation:

As per given we have:

Null hypothesis : H_{a}: p\geq0.80

Alternative hypothesis : H_{a}: p

let p be the proportion of firms in the manufacturing sector offer child-care benefits

A random sample of 390 manufacturing firms is selected and 295 of them offered child-care benefits.

sample size : n= 390

sample proportion :  \hat{p}=\dfrac{295}{390}=0.7564

Test statistic for proportion :

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

Substitute the values , we get

z=\dfrac{0.7564-0.80}{\sqrt{\dfrac{0.80(1-0.80)}{ 390}}}

z=\dfrac{-0.0436}{\sqrt{0.000410256410256}}

z=-2.15257752474\approx-2.15

Hence, the value of test statistic = -2.15

Correct option is c. -2.15 .

Hitman42 [59]

Answer:

The answer is $79.45

Step-by-step explanation:

If the given 4.5 percent interest rate is a yearly rate then according to the information in the question, we can calculate Bonnie's money at the end of the three year period as:

   The initial amount x interest rate x time = 70 x 0.045 x 3 = $9.45

So the amount of money after the three year period comes up to $79.45 for Bonnie.

I hope this answer helps.
