At a local college, an admissions officer surveys the incoming class of 1,000 first-year students concerning theirpreference of major. The officer randomly selects 100 of them and asks if they intend to major in liberal arts. Of the100 first-year students, 62 state they intend on majoring in liberal arts. Assuming the conditions for inference havebeen met, what is the 95% confidence interval for the true proportion of first-year students who intend on majoring inliberal arts?|0.38(1– 0.38)0.38+1.96,1000.62(1-0.62)O 0.62 ±1.96,1000.38(1-0.38)0.38±1.6510000.62(1-0.62)0.62 ±1.651000

We have given that, Favorable cases (X) = 62 and sample size (n) = 100 Then, We will find the 95%…

You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 371 randomly selected caterpillars observed, 49 lived to become butterflies. Round answers to 4 decimal places where possible. With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between ____ and ____ If many groups of 371 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.

Explain what "98% confidence" means in a 98% confidence interval. What does "98% confidence" mean in a 98% confidence interval? CHU OA. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 98 of the intervals to include the parameter and 2 to not include the parameter. OB. The confidence interval includes 98% of all possible values for the parameter OC. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 98%. The probability that it does not is 2% OD. The value of the parameter lies within 98% of a standard deviation of the estimate.
