2:08 LTE coursework course.work location. A random sample of 40 customers at the campus location will be selected as well as an independent random sample of 40 customers at the downtown location and each will be asked whether or not they have used the free Wi-Fi while at that bagel shop in the past. The results will be used to assess if the percentage of campus shop customers who have used the free Wi-Fi is higher than the percentage of downtown shop customers who have used the free Wi- The data were statistically significant at 5% and at 1%. O p-value = 0.001 O p-value = 0.003 O p-value = 0.017 O p-values 0.027 O p-value = 0.045 p-value = 0.052 O p-values 0.067 O p-value = 0.079 O p-value = 0.12

Explanation / Answer

Ans:

1)As,data was significant at 1% and 5%,so p-value should be less than 0.01 and 0.05,hence strictly less than 0.01

(when p-value<alpha,we reject H0 i.e data is significant)

so,possible p-values may be 0.001,0.003 as both are less than 0.01

2)As,data is significant at 10% but not at 5%,it means that p-value should be grater than 0.05 but less than 0.1

So,possible p-values may be 0.052,0.067 or 0.079
