From a large number of actuarial exam scores, a random sample of 275 scores is selected, and it is found that 206 of these 275 are passing scores. Based on this sample, find a 90% confidence interval for the proportion of all scores that are passing. Then complete the table below. Carry the intermediate computations to at least three decimal places. Round the answers to two decimal places. (a) What is the lower limit of the 90% confidence interval? (b) What is the upper limit of the 90% confidence interval?

= 1 = 2 F3 Lower limit: Upper limit: 4 In a sample of 200 college seniors, 160 responded positively when asked if they have spring fever. Based upon this, compute a 90% confidence interval for the proportion of all college seniors who have spring fever. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) X Ś
A 95% confidence interval for a proportion is (0.62, 0.88). From this we can infer: The population proportion is 0.75 The population proportion is equal to the sample proportion O The population proportion is between 0.62 and 0.88 O The population proportion is likely to be between 0.62 and 0.88
You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 405 randomly selected caterpillars observed, 54 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 405 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about percent will not contain the true population proportion.
Suppose you take a random sample of n = 80 Douglas College students and ask each student their age. You find that the mean age of students in this sample is X = 22.0375 years and the sample standard deviation is s = 3.2014 years. Fill in the blanks (rounding to four decimal places): The 95% confidence interval for the mean age μ of all Douglas College students is from ______ years to ______ years.
