Answer:
paul will spend 33
Step-by-step explanation:
66-43
Answer:
no of box multiply by no of granolas then subtract 39 bars
8×9=72
72-39=33
Answer:
Test statistic = - 0.851063
- 2.520463
Step-by-step explanation:
H0 : μ ≥ 15
H1 : μ < 15
Sample mean, xbar = 14.5
Sample standard deviation, s = 4.7
Sample size = 64
Teat statistic :
(xbar - μ) ÷ (s/√(n))
(14.5 - 15) ÷ (4.7/√(64))
= - 0.851063
The critical value at α = 0.05
Using the T - distribution :
Degree of freedom, df = 64 - 1 = 63
Tcritical(0.05, 63) = 1.6694
Test statistic - critical value
-0.851063 - 1.6694
= - 2.520463
To decrease an amount by 7% what single multiplier would you use. You want 7% less than 100%, so the answer is (100%-7%)=93% =0.93. Hope I helped!
