Answer:
Step-by-step explanation:
The null hypothesis is
H0: μ = 32.6
The alternative hypothesis is
Ha: μ ≠ 32.6
The calculated test statistic is 2.66 for the right tail and - 2.66 for the left tail
Since the critical values for both tails is ± 2.145, we would compare the critical values with the test statistic values
In order to reject the null hypothesis, the test statistic must be smaller than - 2.145 or greater than 2.145
Since - 2.66 < - 2.145 and 2.66 > 2.145, we would reject the null hypothesis.
Therefore, Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.
2) Test statistic: t = 2.66. Critical values: t = ±1.96
Since - 2.66 < - 1.96 and 2.66 > 1.96, we would reject the null hypothesis. Then
Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.
Answer:
The Ration of length 2.0 meters to the length 1.2 meters = 5 : 3
Step-by-step explanation:
The given two length are 2.0 m and 1.2 m
Length L1 = 2.0 m And
Length L2 = 1.2 m
SO, The ratio of L1 : L2 =
Or, The ratio of L1 : L2 =
∴ The ratio of L1 : L2 =
Hence The ratio of L1 : L2 is 5 : 3 Answer
I believe the answer is 72 books
