Here are the parameters for this problem

For your second post, reply to another student's first post and complete the problem with these steps:

d. decide whether to reject or fail to reject the null hypothesis. based on the test statistic or the p-value

e. interpret the decision in the context of the original claim.

Here is the post that requires the reply with d. and e. completed as stated above

6. Fast Food: A fast-food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 920 milligrams. A random sample of 44 breakfast sandwiches has a mean sodium content of 925 milligrams. Assume the population standard deviation is 18 milligrams. At = 0.10, do you have enough evidence to reject the restaurant's claim?

The claim is that in one of its breakfast sandwiches there is no more than 920 milligrams. This is a right-tailed test because the claim is less than or equal to 920, and the sample is 925. The critical value is 1.28, this is less than the test statistic z at 1.84. So we can say there is enough evidence to reject the restaurants claim. The screenshots of the week 6 calculator below are highlighted with were I input and gained information to answer the question completely. It was very helpful to follow along with the instructors first question video, as I was able to plug in my data right along with her.

HO= 920

HA= 925

Critical Right-Tailed Value = 1.28

Test Statistic z = 1.84
