Answer #1

TOPIC:Central limit theorem and probability.

The average score of all golfers for a particular course has a
mean of 73 and a standard deviation of 5. Suppose 100 golfers
played the course today. Find the probability that the average
score of the 100 golfers exceeded 74. Round to four decimal
places.

The
average score of all golfers for a particular course has a mean of
61 and a standard deviation of 3.5. Suppose 49 golfers played the
course today. Find the probability that the average score of the 49
golfers exceeded 62

The average score of all pro golfers for a particular course has
a mean of 70 and a standard deviation of 3.0. Suppose 36 golfers
played the course today. Find the probability that the average
score of the 36 golfers exceeded 71.

A) Describe the sampling distribution of

p=0.3
B) assume that blood pressure readings are normally distributed
with a mean of
124
and a standard deviation of
6.4. If 64 people are randomly selected, find the probability
that their mean blood pressure will be less than 126.

Historically, the average score of PGA golfers for one round is
71.1 with a standard deviation of 3.05. A random sample of 73
golfers is taken. What is the probability that the sample mean is
greater than 71? Question 9 options: 1) 0.4869 2) 0.6103 3) 0.3897
4) 0.5131 5) -0.0746

Historically, the average score of PGA golfers for one round is
66.4 with a standard deviation of 1.79. A random sample of 72
golfers is taken. What is the probability that the sample mean is
between 66.14 and 66.4?
Question 9 options:
1)
1.0063
2)
The sample mean will never fall in this range.
3)
0.0577
4)
0.6089
5)
0.3911

b) If we know that the length of time it takes a college student
to fingd a parking spot in the library parking lot follows a normal
distribution with a mean of 3.5 minutes and a standard deviation of
1 minute, find the probability that a randomly selected college
student will take between 2 and 4.5 minutes to find a parking spot
in the library parking lot.
c) The mean score of all pro golfers for a particular course has...

Descriptive analysis revealed that the mean Test 1 score of all
statistics students was 71.23, with a standard deviation of 19.04.
Furthermore, assume that the distribution of all students' Test 3
scores is normally distributed.
Determine the z-score that corresponds to Test 3 score of 83. Round
the solution to two decimal places.
z=
Determine the following probabilities. Round all probability
solutions to four decimal places.
Determine the probability that a randomly selected student scored
exactly a 59 on Test...

A normal population has a mean of 77 and a standard deviation of
5. You select a sample of 48.

1. a) The average score of golfers competing in the ACME INC
Tournament is 71.5. In golf, the goal is to get the lowest score. A
golfer knows he needs to be in the bottom 20% of scores in order to
qualify for the next round of the tournament. If the standard
deviation of the gold scores os 3.12 , he needs to score below what
value in order to advance to the next round?
b) The average math SAT...
