Hypothesis testing-z and p value

Reference no: EM13112404

A furniture store claims that a specially ordered product will take, on average, mean= 35 days (5 weeks) to arrive. The standard deviation of these waiting times is 5 days. We suspect that the special orders are taking longer than this. To test this suspicion, we track a random sample of 90 special orders and find that the orders took a mean of 36 days to arrive. Can we conclude at the 0.1level of significance that the mean waiting time on special orders at this furniture store exceeds 35 days?

Perform a one-tailed test.

The H0 is mean = 35

The H1 is mean >35

We do a Z-test

The value of the test statistic (rounded to at least the third decimal) is 1.897

The p-value is (rounded to at least the third decimal) is?
