Is Breakfast Significantly Different/More Caloric Than Lunch?
Known from Data Set: Breakfast x̅=2.9
Lunch µ=2.14
σ=0.489
n=30
99% confidence level
α=.01
d.f.= 29
Formulate Hypothesis:
Ho: x̅ = 2.4 The breakfast calorie average is statistically the same as lunch
Ha: x̅ ≠ 2.4 The breakfast calorie average is not statistically the same as lunch
t=2.7564
Formula
z = (x̅ – µ)/σ/sqrt(n) (2.9-2.14)/0.489/sqrt(30) = 8.513 8.513 is significantly past our critical point.
We know with a 99% confidence level, we may reject the Null Hypothesis, Breakfast calorie content is not the same as Lunch calorie content.
