Answer:
p=0.063
Step-by-step explanation:
Let X be number of the certain brand of jelly beans that are made so that each package contains about the same number of beans.
X is N(375, 8)
YOu are collecting a sample size of
n = 8
Findings from the sample
(Left tailed test at 5% level)
Since sample size is small though sigma is known we use Z test, since norm
Mean difference = -5
Std error =
Test statistic t = mean diference / std error =
df = n-1 =5
p value = 0.063
Answer:
x = 42
Step-by-step explanation:
The angle between the tangent and the secant is
difference of the measure of the intercepted arcs, that is
x = 0.5( 136 - 52) = 0.5 × 84 = 42
