Help me please this is not easy for me 504
My name is Ann [436]
Let, S = Shirt, J = Jeans

14a) 
This question asks for the discount to be added after everything else.
S= 12   J=19

3S + 2J -3 = Cost with discount applied to total
^ This expression adds to costs, then takes away the $3 discount as the end.

14b)
This questions says the discount is added on every shirt, we get a similar expression:
3(S-3) + 2(J-3) = Cost with discount applied on every shirt and jeans

14c)
The difference between a) and b) is that:
 > the discount in a) is applied on the total, meaning a lower discount
> the discount for b) is applied on each shirt and jeans, meaning a greater discount

14d)
If I were the shop owner I would be more specific of what the discount included, for example we don't know whether to discount each product (shirts and jeans) or only discount the total.

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 .
