Question

Suppose you analyzed the aver ace monthly credit card bill of Visa credit card customers using two randomly selected samples one with ISO Visa credit card customers (Sample #1) and one with 97 Visa credit card customers (Sample #2). Every a edit card customer m Sample #1 had a monthly credit card bukk ir $ 1810. Sample $2, on the other hand, had an average monthly credit card bill of $ 1850 with a variance of 1,301,368 (s)^2 you combined these samples into one... What would be the combined monthly credit card bill average? What is the combined monthly credit card bill median? What is the shape of the combined monthly credit card bill distribution? What would be the combined monthly credit card bill standard deviation? Use the Interceptions per Attempt (int / Att) and Win% data for the 8 randomly selected NFL teams below to answer the following question (see page 621 of your textbook for a similar problem.)

Explanation / Answer

TWO SAMPLES ARE GIVEN HERE

A) AVERAGE OF BOTH COMBINED WILL BE (1810+1850)/2 = 3660/2 = 1830

B)SAMPLE 1 HAS 150

SAMPLE 2 HAS 97

COMBINED = 150 + 97 = 247 CREDIT CARDS

MEDIAN IS THE MIDDLE NUMBER OF THE DATA

AND IN THE SAMPLE OF 247

THE MIDDLE NUMBER = 124TH CREDIT CARD

2B) DISTRIBUTION WILL BE A BELL SHAPED

3) STANDARD DEVITION = VARIANCE^(1/2)

VARIANCE = 1301368 ^(1/2) = 1140.77
