Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval is 0.575 to 0.625.
Answer:

Answer:
41.76 meters
Step-by-step explanation:
Usain Bolt's speed = 
= 10.44m/s
=> In 4 seconds Usain Bold can run: 10.44 x 4 = 41.76m
Hint: angle y is adjacent to an angle of 90 degrees adjacent angles add up to 180 degrees
