Question 773722: Hi,
Could you please help me? I'm working on trying to understand the steps to break this all down.
. An industrial engineer would like to determine whether there are more units produced on the afternoon shift than on the morning shift. A sample of 50 morning-shift workers showed that the mean number of units produced was 345, with a standard deviation of 21. A sample of 60 afternoon-shift workers showed the mean number of units produced was 351, with a standard deviation of 28 units. At the .05 significance level we will test if the mean number of units produced on the afternoon-shift is larger.
Is this a one sample test or a two sample test?
Is this a one tail or two tail test?
What is your critical value?
What is H1?
Ua < Um where "m" is morning and "a" is afternoon
Um > Ua
Ua > Um
Ua not equal to Um
What is your test statistic?
If the critical value is on the right of your curve and your test statistic is less than the critical value what will be your decision?
What is your conclusion?
