Answer:
Z = = 1.6
we reject the Null hypothesis
Step-by-step explanation:
The correct test statistic
Assume :
Null Hypothesis : H_0 : p = 0.08
Alternative hypothesis : H_a : p ≠ 0.08
p = proportion of residents that are unemployed
x = unemployed residents = 22
n = sample size = 200
To get the sample of the population that is unemployed we use this equation
= 22 / 200 = 0.11
now we apply the test of of significance of single proportion
= Z =
therefore Z = = 1.6
Therefore we reject the Null hypothesis
The correct question is
<span>What is the approximate circumference of the largest circle that could be cut out of an 8 1/2-inch by 11-inch piece of paper? use 3.14 for p and round to the nearest inch?
we know that
the circumference=pi*D
where D is the diameter
dimensions piece of paper
8 1/2 in x 11 in----> 8.5 in x 11 in
so
</span><span>The longest diameter (that remains on the paper) would be 8.5 inches
circumference=3.14*8.5-----> 26.69 in------> nearest inch----> 27 in
the answer is
27 in</span>
