Answer:
Option b.
Step-by-step explanation:
Sample size n = 9
sample mean = 217.222
Standard deviation s = 1.202
alpha a = 0.025
H0 : u = 216
H1 : u > 216 ( claim)
Now run a T test and result is :
Test statistic, t =
t =
=
t = 3.0509
Critical value = t(a,n-1) = t(0.025,9-1)
= 2.306
Since t > critical value, Hence reject H0.
Option b. is the answer. Yes, because computed t is greater than the critical value.
12 boxes
each contains 24 cans of soup
number of cans total=number of boxes times number of cans per box
total=12 times 24
tota=288
answer is 288 cans

Answer:
D
Step-by-step explanation:
40 / 2 = 20
area = (pi)*r*r
20*20*(PI) = circle area
it's half of the area, so you need to divide it by 2
