Answer:
Part A:24140 PartB: 16865
Step-by-step explanation:
multiply the total number of people by the decimal form of the percentage (move decimal left two places)
71000*.34=24140
71000*.425=30175
then to find the other number you must add the two before then subtract from the total
24140+30175=54135
71000-54135=16865
Answer:
the mean and the standard deviation is 0.92 and 0.01808 respectively
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean is 0.92
And, the standard deviation is
= √0.92 × (1 - 0.92) ÷ √225
= √0.92 × 0.08 ÷ √225
= √0.0736 ÷ √225
= √3.27
= 0.01808
Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively
