Answer:
We need a sample size of 564.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
The margin of error is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Based upon a 95% confidence interval with a desired margin of error of .04, determine a sample size for restaurants that earn less than $50,000 last year.
We need a sample size of n
n is found when 
So
Rounding up
We need a sample size of 564.
Answer:
Step 1: multiply
10*10=100*10=1000*10=10000
Step 2: write 1st one out.
(8*10000)
Step 3: multiply
8*10000=80000

Step 1: multiply
10*10=100*10=1000*10=10000*10=100000*10=1000000*10=10000000*10=100000000*10=1000000000*10=10000000000*10=100000000000*10=1000000000000
step2: multiply
2*100000000000=200000000000
step 3: write it out
80000*200000000000
step 4: solve
80000*200000000000=1.6 to the power of 17
Step-by-step explanation:
so your answer is
1.6 to the power of 17
that was a lot yw
