The number of entrees purchased in a single order at a noodles & company restaurant has had an historical average of 1.35 entrees per order. on a particular saturday afternoon, a random sample of 26 noodles orders had a mean number of entrees equal to 1.4 with a standard deviation equal to 0.7. at the 1 percent level of significance, does this sample show that the average number of entrees per order was greater than expected?

a) calculate the t statistic (round your answer to 2 decimal places.)
b) find the p-value. (round your answer to 4 decimal places.)

a) 0.3571

b) The p-value is 0.362007.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 1.35

Sample mean, = 1.4

Sample size, n = 26

Alpha, α = 0.01

Sample standard deviation, s = 0.7

First, we design the null and the alternate hypothesis

We use One-tailed t test to perform this hypothesis.

a) Formula:

Putting all the values, we have

b) The p-value at t-statistic 0.3571 and degree of freedom 25 is 0.362007.

true

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
