Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students () = 69, number who liked the new method (x) = 38
For female students: number of female students () = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method () is given as:
The probability that a female student like the new method () is given as:
c = 95%, α = 1 -c = 0.05
the difference between the proportions of male and female students who like the new method better = ± = ± = (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
h + 2d = 6
2h + 2d = 9.60
-2h - 4d = -12
2h + 2d = 9.60
- 2d = - 2.4
d = $1.20
Answer:
s<10
Step-by-step explanation:
If s is less than 10, 10 would be greater making s<10.
Hope this helps!!
The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
