Answer:
There is not enough evidence to support the claim that the bags are under filled.
Step-by-step explanation:
Given :
Population mean, μ = 433
Sample size, n = 26
xbar = 427
Variance, s² = 324 ; Standard deviation, s = √324 = 18
The hypothesis :
H0 : μ = 433
H0 : μ < 433
The test statistic :
(xbar - μ) ÷ (s/√(n))
(427 - 433) / (18 / √26)
-6 / 3.5300904
T = -1.70
The Pvalue :
df = 26-1 = 25 ; α = 0.05
Pvalue = 0.0508
Since Pvalue > α ; WE fail to reject the Null and conclude that there is not enough evidence to support the claim that the bags are underfilled
Answer:
a) 90 cubic foot
b) 90 cubic foot = 667.62 gallons
c) $3.3381
Step-by-step explanation:
a)
volume of rectangular hot tub
= 6*5*3
= 90 cubic foot
b)
1 cubic foot = 7.418 gallons
90 * 1 cubic foot = 90 * 7.418 gallons
90 cubic foot = 667.62 gallons
c)
$5 = 1000 gallons
($5 / 1000) = (1000 / 1000) gallons
.005 * 667.62 = 1 * 667.62 gallons
$3.3381 = 667.62 gallons
Answer:
sqrt 256 is a rational number, so that one is not an irrational number.
Order of operations rules require that you do the exponentiation first.
