Answer:
The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.
Solution:
Number of hours after 5 a.m.: x
At 10 a.m.→x=10-5→x=5
yˆ=−0.37(5)^2+6.15(5)+52.3
yˆ=−0.37(25)+30.75+52.3
yˆ=−9.25+30.75+52.3
yˆ=73.8
Answer: The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.
Answer:
At sample size of 752 is needed.
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
.
The margin of error is:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
What size of sample is needed?
A sample size of n is needed.
n is found when M = 0.03.
We do not have a estimate for the true proportion, so we use
, which is when we are going to need the largest sample size.






Rounding up
At sample size of 752 is needed.
