Aim

To test that there is any difference in the shopping pattern of the people on Friday the 13th and Friday the 6th.

Variables

The variables involved in this test are shopping data set, Date, and location. The variables of date, location are independent and the shopping data set is dependent. The test is to analyze that there exists any dependency between the shopping data set a variable and the variable of dates.

Statistical test

The most appropriate statistical technique to test the hypothesis for this situation is the paired t-test. The samples are random but dependent on each other. The shopping data set was recorded for the same location for two various dates. Hence the samples are dependent. So we have to use the paired t-test.

Hypothesis Testing

Null hypothesis: There is no difference between the shopping pattern on Friday the 13th and Friday the 6th.

Alternate hypothesis: There is a significant difference between the shopping pattern on Friday the 13th and Friday the 6th.

H0: µ6 = µ13 vs H1: µ6 ≠ µ13 where µ denotes the population means of the number of shoppers and the suffix denotes the dates.

Level of significance: As no level of significance is specified the default value of 5% is considered.

From the data set given, the mean number of peoples on Friday the 6th is 4970.51, the mean number of peoples on Friday the 13th is 5017 and the number of samples is 45.

Hence D = Difference between the sample means = 5017 – 4970.51 = 46.49.

SD = 174.98

Degrees of Freedom: The degree of freedom is n – 1 = 45 -1 = 44.

Result: The critical values for the test are +2.32 and -2.32 as the test is two-tailed. Since the obtained value 1.782 lies between the critical values, we have no evidence against the null hypothesis and it is reasonable to conclude that there is no difference between the shopping pattern on Friday the 13th and Friday the 6th.
