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)
Hope this helps!

Answer: 7 books
Step-by-step explanation:
Start by subtracting 26 and 5 which gives you 21
Then you want to divide 21 and 3 which leaves you with 7

Answer:
Two possible sets of answers.
5 men, 11 women and 42 children, or
10 men, 2 women and 88 children
Selamat Sadhya!
Step-by-step explanation:
M = number of men
W = number of women
100-M-W = number of children
Total number of pappadas
5M+3W+(100-M-W)/2 = 100
Solve for W
W = (100-9M)/5 .......................(1)
Examine equation (1).
In order to have W as a whole number, M must be multiple of 5
Therefore M = 5 or 10
If M = 5, W = (100-45)/5 = 11 and children = 100-5-11 = 84
If M = 10, W = (100-90)/5 = 2 and children = 100-10-2 = 88
64 dollars is the tax, the total cost would be $864.
Use this for percentages.
