Answer:
3/8 is #1
3/16 is #2
4/9 is #3
Step-by-step explanation:
First add all the items together:
6 + 4 + 7 + 4 = 21
then we compare 6 and 21 and look for common factors, 6 and 21 have the common factor 3 so we divide them both by 3 to get 2 and 7. since 2 and 7 have no common factors our answer is
2:7
This means for every 2 cans of fruit there are 7 total items and vice versa.
Answer:
His 95% confidence interval is (0.065, 0.155).
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:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
His 95% confidence interval is (0.065, 0.155).
Can you please write what the question is? I need to know what the category is to figure out which one does not belong.
