Answer #1


Total number of sample (n) = 190
number of favourable events (X) = 380

We are interested in testing the hypothesis

Decision Rule: Reject the null hypothesis if the test statistic value is less than the critical value -1.6448536269514722 or greater than the critical value 1.6448536269514722
The statistic value, 40.3788 is greater than the critical values -1.6448536269514722 .
Therefore, we fail to reject the null hypothesis.
