Question 1196773: x = 27
n = 200
Ho: p = 10%
HA: p > 10%
α = 0.01

Test statistic: z = 1.6499
p-value = 0.0495
Reject Ho in favor of HA
There is enough evidence to show that the proportion is significantly greater than 10%.



Test statistic: z = 1.6499
p-value = 0.0495
Fail to reject Ho
There is not enough evidence to show that the proportion is significantly greater than 10%.

Test statistic: z = 1.6499
p-value = 0.0086
Reject Ho in favor of HA
There is enough evidence to show that the proportion is significantly greater than 10%.

Test statistic: z = 1.6499
p-value = 0.0086
Fail to reject Ho
There is not enough evidence to show that the proportion is significantly greater than 10%.

Hi
Ho: p = 10%
Ha: p > 10%
α = 0.01  critical value = 2.326
As 1.6499 < 2.326  it must fall in the category of "Fail to Reject."

Test statistic: z = 1.6499
p-value = 0.0495   p-value >  .01   Also "Fail to reject"
Fail to reject Ho
There is not enough evidence to show that the proportion is significantly greater than 10%.
