Explanation / Answer

Test and CI for One Proportion

Test of p = 0.11 vs p < 0.11

99% Upper

Sample X N Sample p Bound Z-Value P-Value

1 181 1855 0.097574 0.113602 -1.71 0.044

From above minitab Output:

Test statistic is -1.71.

Critical z value -

For the left-tailed case.The z-critical value for a left-tailed test, for a significance level of =0.01 is

zc=2.33

Test Statistic Value -1.71 > Critical value zc -2.33 (P-value 0.04 > alpha 0.01) so we do not reject the null hypothesis. We conclude that there is not sufficient evidence to support the claims less than 11% of trips include a parking visit.

Hope this will b ehelpful. Thanks and God Bless You :-)
