Answer: (0.760, 0.820)
Step-by-step explanation:
Let p be the population proportion of all adults feel that "education and our schools" is one of the top issues facing California.
Given : 79% (actual results are 400 out of 506 surveyed) of California adults feel that "education and our schools" is one of the top issues facing California.
i.e.Sample size : n= 506
Sample proportion :
Critical value for 90% confidence interval ( Using z-value table) :
Now, the 90% confidence interval for the population proportion will be :
i.e.
i.e.
Hence, the 90% confidence interval for the population proportion= (0.760, 0.820)
For this case we have the following linear equation:
d = 15.7p + 2.0
Where,
p: number of people
d: total bill
We note that the slope of the equation is:
m = 15.7 $ / person
Therefore, the amount of the bill increases if the number of people grows.
Answer:
b) The model predicts that for each additional person at a table, the total bill increases by $ 15.70.
