Answer:
Given:You sample 160 men, and 25% own cats
You sample 120 women, and 20% own cats.
To Find : Find the test statistic, rounded to two decimal places.
Solution:
You sample 160 men, and 25% own cats.
No. of men have cats =
=
So,
You sample 120 women, and 20% own cats.
No. of women have cats =
=
So,
We will use Comparing Two Proportions
Let and be the probabilities of men having cat and women having cat receptively

Answer:
<u><em>Page # 1:</em></u>
1)
= 9.38
2)
= 9.28
3)
= 5.48
4)
= 8.33
<em><u>Page # 2:</u></em>
1)
= 1
2)
= 2
3)
= 5
The problem is,
→ (2√3)/√12
Let's simplify the problem,
→ (2√3)/√12
→ (2√3)/(√4 × √3)
→ (2√3)/(2 × √3)
→ (2√3)/(2√3) = 1
Hence, the answer is 1.
Answer: since the toy is marked down 15%,
you do p*.85
