Based on historical data, your manager believes that 34% of the
company's orders come from first-time customers. A random sample of
71 orders will be used to estimate the proportion of
first-time-customers. What is the probability that the sample
proportion is less than 0.32?
Note: You should carefully round any z-values you calculate to 4
decimal places to match wamap's approach and calculations.
Answer =0.3555 was wrong
B.Based on historical data, your manager believes that 32% of
the company's orders come from first-time customers. A random
sample of 138 orders will be used to estimate the proportion of
first-time-customers. What is the probability that the sample
proportion is between 0.21 and 0.35?
Note: You should carefully round any z-values you calculate to 4
decimal places to match wamap's approach and calculations.
Answer = 0.7736 was the wrong answer (Enter your answer as a number
accurate to 4 decimal places.)
C.You want to obtain a sample to estimate a population
proportion. At this point in time, you have no reasonable estimate
for the population proportion. You would like to be 90% confident
that you esimate is within 2.5% of the true population proportion.
How large of a sample size is required?
n =
Do not round mid-calculation. However, use a critical value
accurate to three decimal places.
