How the Data Was Obtained
To obtain the samples for my study I went to Malley's on the 13th, 14th, 15th, and 16th of May, 2014. I sat at a table where I had a good view but was descrete about my doings. I kept a stop watch with me and started the timer as soon as the clock hit 4 o' clock. Every time someone walked in, I would mark a tally on my paper under the category they followed; either men or women, at that specific 15 minute interval. When the timer stopped after 15 minutes, I would resart it and count the next fifteen minutes. I did this same process until 6 o' clock all 4 of those days.
The population I took my samples from was any man or woman that walked into the Malley's store. Every day, I would have 9 samples frmom within the 2 hours I spent at the store. My population of interest does not get any more specific than any man or woman that comes into the store.
Hypothesis Test Results

µ1 = the
true mean number of men that go to
Malley’s within a 15 minute interval.
µ2 =the true mean number of women that go to
Malley’s within a 15 minute interval. |

Conclusion: We
fail to reject the null hypothesis at the
.05 level of significance
because the p-value is > α.
Therefore, there is not
sufficient evidence to say that the true mean number of men
that go to Malley’s within a 15 minute interval is different
than the mean number of woman that go to Malley’s within a
15 minute interval. |
