Answer:



Since the p value is lower than the significance level we have enough evidence to conclude that the true means are different at 5% of significance
Step-by-step explanation:
Data given
sample mean for group 1
sample mean for group 2
sample size for group 1
sample size for group 2
sample deviation for group 1
sample deviation for group 2
Solution
We want to check if the two means are equal so then the system of hypothesis are:
Null hypothesis: 
Alternative hypothesis: 
And the statistic is given by:

And replacing we got:

The degrees of freedom are given by:

And the p value would be:

Since the p value is lower than the significance level we have enough evidence to conclude that the true means are different at 5% of significance
Answer:
m∠1 = 81
m∠2 = 99
Step-by-step explanation:
The angles are supplemaentary and therefor sum to 180
3x + (x + 72) = 180
4x + 72 = 180
4x = 108
x = 27
m∠1 = 3x
m∠1 = 27(3)
m∠1 = 81
m∠2 = x + 72
m∠2 = 27 + 72
m∠2 = 99
Answer:
<4
Step-by-step explanation:
Vertical angles are formed by the same lines and share a vertex but are opposite.
< HEF also called <6 is a vertical angle to < 4
