Answer:
The 98% confidence interval estimate of the proportion of adults who use social media is (0.56, 0.6034).
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 
.
Of the 2809 people who responded to survey, 1634 stated that they currently use social media.
This means that 
98% 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:
The 98% confidence interval estimate of the proportion of adults who use social media is (0.56, 0.6034).
Answer:
8.5
Step-by-step explanation:
Given the expression 12.75/1.5. The technique in solving the division expression is as shown
First we can write the decimals as fraction as shown;
12.75 = 1275/100
1.5 = 15/10
12.75/1.5 = (1275/100)÷(15/10)
12.75/1.5 = 1275/100×10/15
12.75/1.5 = 1275/10 × 1/15
12.75/1.5 = 1275/150
12.75/1.5 = 8.5
Hence the result of the division is 8.5
