A random sample of 80 voters found that 44% were going to vote for a certain candidate. Find the 90% limit for the population proportion of voters who will vote for that candidate?
a. 39.4% < p < 48.6%
b. 34.9% < p < 53.1%
c. 35.9% < p < 52.1%
d. 36.9% < p < 51.1%
Compute a 95% confidence interval for the population mean, based on the sample 25, 27, 23, 24, 25, 24 and 59. Change the number from 59 to 24 and recalculate the confidence interval.
Mean=63.6 Standard deviation=2.5 If 36 data points are arbitrarily chosen, determine the probability that mean is less than 64.
Use the Rare Event Rule. Does the evidence support the claim?
