Answer: 24
Step-by-step explanation:
6, 12, 18, 24
8, 16, 24
Answer:
Step-by-step explanation:
Given that:
Population Mean = 7.1
sample size = 24
Sample mean = 7.3
Standard deviation = 1.0
Level of significance = 0.025
The null hypothesis:

The alternative hypothesis:

This test is right-tailed.

Rejection region: at ∝ = 0.025 and df of 23, the critical value of the right-tailed test 
The test statistics can be computed as:



t = 0.980
Decision rule:
Since the calculated value of t is lesser than, i.e t = 0.980 <
, then we do not reject the null hypothesis.
Conclusion:
We conclude that there is insufficient evidence to claim that the population mean is greater than 7.1 at 0.025 level of significance.
Answer:
x = 6
Step-by-step explanation:
Answer:
1360 cm2
Step-by-step explanation:
It is still a rectangle, just slanted. So straiten it out a solve it like a normal area problem:
34 x 40 = 1360 cm2
