Answer:
Step-by-step explanation:
<em>Step 1: Define significance level</em>
In this hypothesis testing problem, significance levels α is selected: 
, the associated z-value from Laplace table:
Φ(
) = α - 
=> = 
<em>Step 2: Define null hypothesis (</em>
<em>) and alternative hypothesis (</em>
<em>)</em>
: rate of flu infection 
= 8.3% or 8.3/100 = 0.083
: rate of flu infection < 8.3% or 8.3/100 = 0.083
<em>Step 3: Apply the formula to check test statistic:</em>
with 
is actual sampling percent, is rate of flu infection of , 
is number of samples.
The null hypothesis will be rejected if 
<em>Step 4: Calculate the value of K and compare with </em>
We have 
=>This is good evidence to reject null hypothesis.
=> The actual rate is lower. (As states)

Answer:
answer=11 cm.
Step-by-step explanation:
Answer:
x = -1
Step by step explanation:
Distribute 6
6x-12= -18
Add 12 to both sides
6x= -6
Divide both sides by 6
x= -1

Which of the following lists shows all the factors of 36? 2, 3, 4, 6, 9, 12, 18 1, 2, 3, 4, 9, 12, 18, 36 1, 2, 3, 4, 6, 9, 12,
MAVERICK [17]
<span>1, 2, 3, 4, 6, 9, 12, 18, 36
36 = 6*6 = 2*2*3*3
if you list out all the combinations of those factors, you'll get 7 factors: </span><span>1, 2, 3, 4, 6, 9, 12, 18, 36</span>
