Estimate population mean (σ is known): A biologist studying a colony of beetles selects and weighs a random sample of 20 adult males. She knows that, because of natural variability, the weights of such beetles are normally distributed with standard deviation 0.25 g. Their weights, in grams, are as follows (Round to two decimal places): 5.2 5.4 4.9 5.0 4.8 5.7 5.2 5.2 5.4 5.15.6 5.0 5.2 5.1 5.3 5.2 5.1 5.3 5.2 5.2 (a) Find the mean weight of the beetles in this sample.(b) Find 95% confidence limits for the mean weight of such beetles
Income tax returns one year averaged $1,332 in refunds for taxpayers. One explanation of this figure is that taxpayers would rather have the government keep back too much money during the year than owe it money at the end of the year. Suppose the average amount of tax at the end of a year is a refund of $1,332, with a standard deviation of $725. Assume that amounts owed or due on tax returns are normally distributed. a. What proportion of tax returns show a refund greater than $2,000?(use an excel function ) b. What proportion of the tax returns show that the taxpayer owes money to the government?(use an excel function) c. What proportion of the tax returns show a refund between $100 and $700?(use an excel fucntion)
