Answer:
36
Step-by-step explanation:
Answer:
a) 95%
b) At least 75%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is at least .
a. According to the empirical rule, what percentage of these funds is expected to be within ±2 standard deviations of the mean?
95%
b. According to the Chebyshev rule, what percentage of these funds are expected to be within ±2 standard deviations of the mean?
At least 75%
hmmm i would help but I completely forgot
30 times the number of hours
and
20 times the number of hours the add 10 to your answer
Since it says -81 + -14, you add those two numbers which is 95 the you would add a negative because the highest number is negative. So the answer is -95 ft.
