If the data follows a normal distribution:
Less than 13 ( less than a mean - 1 sigma ): 16% of a population.
0.16 · 200 = 32
Greater than 14 ( 14 is a mean value ): 50% of a population.
0.5 · 200 = 100
Answer:
... about 32 people have hemoglobin levels less than 13, and about 100 people have hemoglobin levels greater than 14.
6 dollar divided per 8 lemons = $0.75
Between 75 and 98.
Step-by-step explanation:
Let's first have a look at the previous data available:
Friday, 27 dunk teachers out of 215 participants (12.5%)
Saturday: 54 dunk teachers out of 417 participants (12.9%)
Sunday: 39 dunk teachers out of 368 participants (10.6%)
So, based on the previous 3 days, she can expect between 10% and 13% will dunk a teacher.
If she has 750 contestants on Monday, the number of winners should then be in the range of 75 (10% of 750) and 98 (13% of 750).
