Jillian is an analyst for a ride sharing app that connects users with drivers. She wonders if drivers in Dallas are more or less likely to cancel rides than drivers in Houston. She takes a random sample of 1000 rides from Dallas and finds that 30 were cancelled. A random sample of 1000 rides from Houston shows 24 cancelled rides. She used these results to test H: Pp = PH versus H, :pp + PH. The test statistic was z = 0.83 and the P-value was approximately 0.41. Assume that all conditions for inference were met. At the a = 0.01 level of significance, is there sufficient evidence to conclude that the proportion of cancelled rides is different between the two cities?
A Yes, since the P-value is greater than 0.01.
B Yes, since the test statistic is greater than 0.01.
C No, since the P-value is greater than 0.01
D No, since the test statistic is greater than 0.01.
