Fail to reject the null hypothesis; there is a statistically significant difference in the number of tickets issued. Ali issued more.
Fail to reject the null hypothesis; there is statistically significant difference in the number of tickets issued. Ali issued more.
Fail to reject the null hypothesis; there is no statistically significant difference in the number of tickets issued.
Reject the null hypothesis; there is not statistically significant difference in the number of tickets issued.
Reject the null hypothesis; there is a statistically significant difference in the number of tickets issued. JT issued more.
