Step-by-step explanation:
Answer:
There is<u> no </u>sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
Null [H0] : chips x = 408
Alternate [H1] : chips x < 408
t = ( x' - u ) / (s / √n)
x' = sample mean , u = population mean, s = standard deviation, n = no. of observations.
(406 - 408) / (21 /√45)
-2 / 3.13
= 0.64
t value for α = 0.01 (one tailed), with degree of freedom = 44 : is 2.41
As calculated t 0.64 < tabulated t 2.41. So we don't reject the null hypothesis & state that chips x = 408
Total perimeter:
2u+7 inches+2u+7 inches+1u+1u
7 inches x 2 = 14 inches
*As there are 2 lengths, there are two sets of "extra" 7 inches.*
(2ux2)+1u+1u=6u
6u=110 inches - 14 inches = 96 inches
1u = 96 inches ÷ 6=16 inches (width)
(2x16 inches)+7 inches=32 inches+7 inches=39 inches
Ans: 39 inches
