<h2>Answer with explanation:</h2><h2></h2>
Let p be the population proportion of orders are delivered within 10 minutes of the time the order is placed.
Then according to the claim we have ,
Since the alternative hypothesis is two-tailed so the hypothesis test is a two-tailed test.
For sample ,
n = 90
Proportion of orders are delivered within 10 minutes of the time the order is placed=
Test statistics for population proportion :-
The p-value : [By using standard normal distribution table]
Since the p-value is greater that the significance level (0.01), so we do not reject the null hypothesis.
Hence, we conclude that we have enough evidence to support the claim that 90% of its orders are delivered within 10 minutes of the time the order is placed.
