Arandom sample of house sizes in major city has a sample mean of x¯=1204.9 sq ft and sample standard deviation of s=124.6 sq ft. use the empirical rule to determine the approximate percentage of house sizes that lie between 955.7 and 1454.1 sq ft. round your answer to the nearest whole number (percent).

About 95% of house sizes that lie between 955.7 and 1454.1 sq ft .

Step-by-step explanation:

According to the empirical rule  about 68% of the data is within one standard deviation of the mean; about 95% of the data is within two standard deviations of the mean ; about 99.7% of the data is within three standard deviations of the mean.

We have given:

Sample mean : x¯=1204.9 sq ft

Standard deviation: s=124.6 sq ft

To find the percentage of house sizes that lie between 955.7 and 1454.1 sqft.

We can write it as

955.7= 1204.9 - 249.2 = 1204.9 - 2(124.6)

and 1454.1  = 1204.9 + 249.2 = 1204.9 + 2(124.6)

Thus, 955.7 is 2 standard deviations left from the means and 1454.1 is 2 deviations right from the mean.

Then by empirical rule , about 95% of house sizes that lie between 955.7 and 1454.1 sq ft .

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

answer is 12345678900987654321234567890987654321
