Answer:
20 people only buy dvds.
Step-by-step explanation:
There are two groups in this problem. One group of people that buys dvds and one that buys blu rays. The total amount of people who buy blu rays is 300, but there's an intersection between the groups and the size of this is 280 people who actually buy both. In order to find out how many people only buy DVDs we first need to figure out how many only buy blu-rays. That is:
people who only buy blu rays = people who buy blu rays - people who buys blu rays and dvds
people who only buy blu rays = 300 - 280 = 20
We can now calculate the amount of people who only buy dvds and that is:
people who only buy dvds =total amount of people - ( people who only buy blu rays + people who buy both)
people who only buy dvds = 320 - (20 + 280) = 320 - 300 = 20 people
Answer:
Step-by-step explanation:
To compare different scores with different means and std deviation, we convert each score into equivalent Z score.
Then comparisons would be easier.
Z = is the conversion factor
a) a score of 38 on a test with a mean of 31 and a standard deviation of 5.8
Z score =
b) a score of 1124 on a test with a mean of 1080 and a standard deviation of 67.7
Z score = 0.65
c) a score of 4709 on a test with a mean of 3960 and a standard deviation of 557.1
Z score = 1.34
Hence we get highest relative score is
a score of 4709 on a test with a mean of 3960 and a standard deviation of 557.1
