Answer:
More cereal
Step-by-step explanation:
The slope = (10-6) / (4-3) = 4
using the general equation y - y1 = m(x - x1) where m = slope and (x1,y1) is a point on the line, we have:-
y - 6 = 4(x - 3)
y = 4x - 12 + 6
y = 4x - 6 (answer)
Answer:
The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
The 90% confidence interval for the proportion of Republican voters that had voted for Mitt Romney is (0.7273, 0.8106). The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
Answer:
Step-by-step explanation:
The probability distribution of sampling distribution is known as it sampling distribution.
The mean and standard deviation of the proportion is given by :-
, where p =population proportion and n= sample size.
Given : According to a survey, 50% of Americans were in 2005 satisfied with their job.
i.e. p = 50%=0.50
Now, for sample size n= 1000 , the mean and standard deviation of the proportion will be :-
Hence, the mean and standard deviation of the proportion for a sample of 1000:
