Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Probability that he jumps a hurdle =
Total number of hurdles = 10
Probability that he knocks down =
So, Probability (knocks down all hurdles ) is given by
Hence, Option 'a' is correct.
Answer:
a) 25
b) 67
c) 97
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample. In this problem,
(a) The desired margin of error is $0.10.
This is n when M = 0.1. So
Rounding up to the nearest whole number, 25.
(b) The desired margin of error is $0.06.
This is n when M = 0.06. So
Rounding up, 67
(c) The desired margin of error is $0.05.
This is n when M = 0.05. So
Rounding up, 97
