The crisis in the real estate market caused the listing prices of homes in certain areas to fall from previous years. A real estate office would like to sample 48 new listings randomly to test the hypothesis that the current listing price average is less than $244,000, the average in the previous year. Assume the standard deviation for the price of homes in this market is $45,000. Complete parts a through d below. a. Explain how Type I and Type II errors can occur in this hypothesis test. A Type I error can occur if the average listing price is rejected. ▼$244,000 and the null hypothesis is rejected. A Type II error can occur if the average listing price is $244,000 and the null hypothesis is not

A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school
