The empirical rule states that in a normal distribution,
68% of data is within 1 std deviation of the mean
95% of data is within 2 std deviation of the mean
99.7% of data is within 3 std deviation of the mean
In this case 95% of the cases would be within two std deviations of the mean
mean - 8 and mean + 8
72 - 8 = 64 and 72 + 8 = 80
then 95% of the scores are between 64% and 80% on the test.
What do you need help with? it helps us to know the question!
If you have a graphing calculator, you can type 37.25/100 then that would equal 0.3725. Then you press the MATH button and select frac. This will give you 149/400
Answer:
B) √5, 5/2, 2.71 (repeating), 2 3/4
Step-by-step explanation:
1) For me, I convert the fractions and squared numbers into decimals
2) 2 3/4 = 2.75
3) √5 (the square root of five) ≈ 2.236
4) 5/2 = 2.5
5) now list the numbers from least to greatest
5) Which number is the least? √5
6) Next? 5/2
7) Next? 2.71 repeating
8) Greatest? 2 3/4
Hope this helps you, good luck with your assignment, and if possible, please mark me brainliest.
