A golf club currently has 350 members that pay annual dues to play golf on the course. Historical records show that 39% of the members use the course at least once a week during the summer season. To verify this, a random sample of 100 members was selected. Complete parts a through d below.
a. Calculate the standard error of the proportion.
(Round to four decimal places as needed.)
b. What is the probability that 32 or more members from the sample used the course at least once a week?
(Round to four decimal places as needed.)
c. What is the probability that between 30 and 40 members from the sample used the course at least once a week?
(Round to four decimal places as needed.)
d. If 50 members from the sample used the course at least once a week, does this support the historical records of course usage? Select the correct choice below and, fill in the answer box to complete your choice.
(Round to four decimal places as needed.)
A.No, since the probability of obtaining a result this large or larger is BLANK , given that the historical records give an accurate estimation of course usage.
B.Yes, since the probability of obtaining a result this small or smaller is BLANK , given that the historical records give an accurate estimation of course usage.
C.Yes, since the probability of obtaining a result this large or larger is BLANK, given that the historical records give an accurate estimation of course usage.
D.No, since the probability of obtaining a result this small or smaller is BLANK, given that the historical records give an accurate estimation of course usage.

Golf-course designers have become concerned that old courses are
becoming obsolete since new technology has given golfers the
ability to hit the ball so far. Designers, therefore, have proposed
that new golf courses need to be built expecting that the average
golfer can hit the ball more than 235 yards on average. Suppose a
random sample of 102 golfers be chosen so that their mean driving
distance is 9 yards. The population standard deviation is 41.7. Use
a 5% significance...

Your company has a contract to perform preventive maintenance on
thousands of air-conditioners in a large city. Based on service
records from previous years, the time that a technician spends
servicing a unit averages one hour with a standard deviation of one
hour. In the coming week, your company will service a simple random
sample of 80 units in the city. You plan to budget an average of
1.1 hours per technician to complete the work. Will this be enough...
