Answer:
Step-by-step explanation:
Null hypothesis: u <= 3 minutes
Alternative hypothesis: u > 3minutes
Using a z test formula, z score is
z = (x - u) / (s/√n)
Where x = 3.1, u = 3, s = 0.5, n = 100
z = (3.1 - 3) / (0.5/√100)
z = (0.1) / (0.5/10)
z = 0.1/0.05
z = 2
To calculate for the p value assuming a 0.05 level of significance, the p value is 0.02275 which is less than 0.05. Thus we will reject the null and conclude that there is enough statistics evidence to show that the mean waiting time of all customers is significantly more than 3 minutes.
