### Question Description

I’m trying to learn for my Statistics class and I’m stuck. Can you help?

### Prompt

- In a previous lab we tested the following hypotheses, $H$
0 : $\mu $= 4.73 and $H$a : $\mu $< 4.73 (where $\mu $ is the mean number of alcoholic drinks consumed by students at a liberal arts college).

In a random sample of 75 students, the mean was 3.93 alcoholic drinks consumed in a week. Here is the StatCrunch output from the hypothesis test.**$\mu $:**Mean of variable**${H}_{}$**$\mu $0 := 4.73

$H$A : $\mu $≠ 4.73

Using this context and the StatCrunch output, explain the meaning of each of the following.**Hypothesis test results**Variable Sample Mean Std. Err. DF T-Stat P-value number of drinks per week 3.9333333 0.43592434 74 -1.8275343 0.0717 - Std. Err (standard error)
- T-stat (T-score)
- P-value

- In a previous matched pairs lab we tested the following hypotheses, where $\mu $ is the mean of the differences in corn yield for a plot of land (
*regular seed minus kiln-dried*): H0: µ = 0 and Ha: µ < 0. In a random sample of 11 seeds of each type, the mean of the differences in the sample was -33.7. Here is a StatCrunch print-out of the hypothesis test.**Paired T hypothesis test:**$\mu $D = μ 1 − : Mean of the difference between Regular seed and Kiln-dried seedμ 2

$H$0 : $\mu $D = 0

$H$A : $\mu $D < 0

Differences stored in column,**Hypothesis test results**Difference Mean Std. Err. DF T-Stat P-value Regular seed - Kiln-dried seed -33.727273 19.951346 10 -1.6904761 0.0609 *Differences*.

Using this context and the StatCrunch output, explain the meaning of each of the following.

- Std. Err (standard error)
- T-stat (T-score)
- P-value.

## Final Answer

Please find answer.Let me know for any clarifications.Good Bye.

1. In a previous lab we tested the following hypotheses,

H 0:

μ = 4.73 and

H a:

μ < 4.73 (where

μ is the mean number of alcoholic drinks consumed by

students at a liberal arts college).

In a random sample of 75 students, the mean was 3.93 alcoholic drinks consumed in a

week. Here is the StatCrunch output from the hypothesis test.

μ: Mean of variable

H 0:
