1. Without looking at the data, make a hypothesis on the effect of children being involved in food preparation. Which group do you think will have higher levels of calories? Why?

* I put H0: mu1=mu2 and H1: mu1 greater than mu 2 . 1 being children participated 2being children that didn't participate. is my thinking correct?

2. Prepare to construct confidence intervals for the means of both sets. Before we make the construction, are there any conditions that need to be satisfied? Are there concerns about using the data set for a confidence interval? Why or why not?

Known:

Experiment conducted to determine effect of children
participating in meal preparation on caloric intake. Two groups
(independent samples). Treatment 1: Children participated.
Trt 2: Did not participate. Data simulated to match means and SDs.
Variables:
Treatment
