Mathematics
Cuyamaca Alcoholic Drinks Consumed by Students at A Liberal Arts College HW

Question Description

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

Prompt

  1. In a previous lab we tested the following hypotheses, LaTeX: H_0H 0: LaTeX: \mu=4.73μ = 4.73 and LaTeX: H_aH a: LaTeX: \mu<4.73μ < 4.73 (where LaTeX: \muμ 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.
    LaTeX: \muμ: Mean of variable
    LaTeX: H_0H 0: LaTeX: \mu=4.73μ = 4.73
    LaTeX: H_AH A: LaTeX: \mu\ne4.73μ 4.73

    number of drinks per week3.9333333 0.43592434 74 -1.8275343 0.0717
    Using this context and the StatCrunch output, explain the meaning of each of the following.
    1. Std. Err (standard error)
    2. T-stat (T-score)
    3. P-value
  2. In a previous matched pairs lab we tested the following hypotheses, where LaTeX: \muμ 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:
    LaTeX: \mu_D=\mu_1-\mu_2μ D = μ 1 μ 2: Mean of the difference between Regular seed and Kiln-dried seed
    LaTeX: H_0H 0: LaTeX: \mu_D=0μ D = 0
    LaTeX: H_AH A: LaTeX: \mu_D<0μ D < 0
    Hypothesis test results
    DifferenceMeanStd. Err.DFT-StatP-value
    Regular seed - Kiln-dried seed-33.72727319.95134610-1.69047610.0609
    Differences stored in column, Differences.

    Using this context and the StatCrunch output, explain the meaning of each of the following.
    1. Std. Err (standard error)
    2. T-stat (T-score)
    3. P-value.

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:
