If a right triangle is 90° , the other acute triangle would be 10° because 90 - 80 = 10
Answer:
Let the 1st group be of students and 2nd group be of faculty.
n1 = 18
\bar{x}_{1} = 8.4
s1 = 7.3
n2 = 15
\bar{x}_{2} = 4.2
s2 = 3.8
1.
H0: =
HA: >
2.
Equality of variance test:
F = s12/s22
= 53.29/14.44
= 3.69
df-num = n1-1 = 17
df-den = n2-1 = 14
p-value = 0..008 < 0.05 i.e.H0 can be rejected and hence we can say that both populations do not have the same variances.
So, test-statistic will be calculated as follows:

3.
df = 26
p-value = 0.0217
4.
E. It confirms the community college results because the p-value is much smaller.

The amount of sales before growth according to the article is $153.85 million
<h3>How to find sales before growth?</h3>
let
- Sales before growth = x
- Percentage growth = 30%
- New sales = $200 million
200 = x + (30% × x)
200 = x + (0.3 × x)
200 = x + 0.3x
200 = 1.3x
x = 200/1.3
x = 153.846153846153
Approximately,
x = $153.85 million
