Answer:

Step-by-step explanation:
To find the slope, rearrange the equation to y=mx+b or y=mx+c.

Subtract 4x from both sides:

Divide 5 on both sides:


In the equation of y=mx+b/y=mx+c, m will be the slope.
Therefore, the slope is 
Answer:
The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).
Step-by-step explanation:
We have to calculate a 96% confidence interval for the proportion.
We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.
The sample proportion is p=0.8.

The standard error of the proportion is:

The critical z-value for a 96% confidence interval is z=2.054.
The margin of error (MOE) can be calculated as:

Then, the lower and upper bounds of the confidence interval are:

The 96% confidence interval for the population proportion is (0.77, 0.83).
Answer:
4/25=0.16=16%
3/11=0.27=27%
Step-by-step explanation:
10% of 13 is 1.3 so 13+1.3= 14.3
