Question

Nutrition Science researchers are concerned about the amount of calories eaten by children who routinely eat at fast food restaurants. A research team collected the following random sample of the number of calories eaten in a day by 7 students who ate a fast food restaurant in a day.

2523    1758    934      2328    2434    2267    2526

1. What is the probability that the actual mean number of calories is greater than 2267.759? HINT: You will need to use the t-table or the Excel function for the t-distribution. (4)

Answer 1

The probability is 0.7501.

2,267.759	hypothesized value
2,110.000	mean Data
581.328	std. dev.
219.721	std. error
7	n
6	df
-0.718	t
.7501	p-value (one-tailed, upper)

Please give me a thumbs-up if this helps you out. Thank you!
