    A. 2.65

    Step-by-step explanation:

    Let mu1 be the mean number of cars that one employee is involved in Detroit plant per day

    And mu2 be the mean number of cars that one employee is involved in Mexico City plant per day

    Null and alternative hypotheses are:

    [tex]H_{0}[/tex]: mu1-mu2=0[tex]H_{a}[/tex]: mu1-mu2>0

    This is one tailed t test and one tailed test statistic is given as 2.650.

    Answer and Step-by-step explanation:

    a. Yes, since the highest standard deviation (s4 = 44.51) is significantly more than double the lowest (s3 = 20.83) is plausible.

    hence, the second option is correct

    (b)  The testing of relevant hypothesis using the output is shown below:

    As we see that

    The 0.05 is more than the F test P-value i.e 0.0000

    So ultimately P-value is less

    Therefore we have to reject the null hypothesis

    Since p-value is less than 0.05 so we reject the null hypothesis.

    Therefore, the third option is correct

    (c)  The construction is shown below:

    Since the sample size is the same so for Tuley's HSD it would also same i.e for each pair

    Now Tuley's HSD is

    [tex]HSD=4.10\cdot \sqrt{\frac{1049}{7}}=50.19[/tex]

    The table that reflects the difference in means in different level is as follows

    Levels       Difference in mean

    4-6             34.85

    4-8             41.92

    4-10            74.15

    4-12           103.96

    6-8            7.07

    6-10           39.3

    6-12          69.11

    8-10           32.23

    8-12           62.04

    10-12            29.81

    Now the table of significant difference is

    Levels       Difference in mean

    4-10                 74.15

    4-12                103.96

    6-12                 69.11

    8-12                 62.04
