Answer:
__63.81 inches__< μ <___65.87 inches__
Step-by-step explanation:
To calculate at 95% confidence interval, we need the Mean of the sample= 64.84
Sample size=32
Standard Deviation=2.9592
95% Confidence Interval: 64.84 ± 1.03
(63.81 inches to 65.87 inches)
"With 95% confidence the population mean is between 63.81 and 65.87, based on 32 samples."
Answer:
The answer is 91.
Step-by-step explanation:
Since 2+2+2=6 and you subtract 2 that would now be 6-2, and that is 4.
87+4=91.
Simply 6-2=4
87+4=91

Using the binomial distribution, it is found that there is a 0.25 = 25% probability he will land on A on the first spin and A and the second.
For each spin, there are only two possible outcomes, either it lands on Sector A, or it does not. The results of each spin are independent, hence, the binomial distribution is used to solve this question.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, we have that:
- The sectors are equal, which means that it is equally as likely to land on each, hence
.
- Saul will spin the wheel twice, hence
.
The probability that both land on A is P(X = 2), hence:


0.25 = 25% probability he will land on A on the first spin and A and the second.
