Answer:
B
Step-by-step explanation:
mean = average. to find it, add all terms, and then divide by the number of terms.
find the mean of group a:
(1+1.5+3+3.2+2.8+1.5+1.8+2.5+2.2)/9 = 2.16
find the mean of group b:
(2+2.5+3.2+3+1.8+2.4+3+1.5+1/8)/9 = 2.1694
group b is larger.
answer = b
9. The experimental probability that it will rain on any given day in Houston Texas is about 15%.
Thus, out of 365 days, 15% of that are the predicted days the it will rain in the Place.
=> 365 days is the total number of days in a year
=> 15% is the predicted days to rain
=> 365 * .15 = 54.75
Since this is a decimal number, let’s round this off to 55 days.
Why 55 because the value of tenths is more than 5.
