Answer:
Yes, we reject the auto maker's claim.
Step-by-step explanation:
H0 : μ ≥ 20
H1 : μ < 20
Sample mean, xbar = 18 ;
Sample size, n = 36
Standard deviation, s = 5
At α = 0.01
The test statistic :
(xbar - μ) ÷ s /sqrt(n)
(18 - 20) ÷ 5/sqrt(36)
-2 /0.8333333
= - 2.4
Pvalue from test statistic : Pvalue = 0.00819
Pvalue < α
0.00819 < 0.01
Hence, we reject the Null
Answer:
367.2 cm²
Step-by-step explanation:
First, you need to find the area of the lateral surfaces, since each one is a 5cm by 6cm rectangle, all you need to do is multiply to find the area of one of them, and then multiply by 6 to find the area of all 6 sides.
lateral area = 5cm * 6cm * 6
lateral area = 30cm² * 6
lateral area = 180 cm²
Next, you need to find the total surface area by multiplying the area of the base by two and adding that to the lateral surface area.
SA = 180cm² + 2(93.6cm²)
SA = 180cm² + 187.2cm²
SA = 367.2cm²
The total surface area is 367.2 cm².
