You will find the area the square and then find out what 4/5 of that area is.
A = bh
     6 cm x 6 cm 
A = 36 square cm
4/5 of 36 square cm
4/5 x 36
28 4/5 square cm
The area of the rhombus is 28 4/5 square cm.  Use this to solve for the height of the rhombus.
A = bh
<u>28 4/5</u> = <u>6 x h</u>
6            6
h = 4 4/5 cm
The height of the rhombus is 4 4/5 cm.

As per given we have:
Null hypothesis :  
 
Alternative hypothesis :  
 
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 :  
Test statistic for proportion :

Substitute the values , we get



Hence, the value of test statistic = -2.15
Correct option is c. -2.15 .
