Suppose that a random sample of 20 recently sold houses in a certain city has a mean sales price of $300,000 with a standard deviation of $7000. Under the assumption that the house prices are normally distributed find a 99% confidence interval for the mean sales price of all houses in the community. Then find the lower limit in upper limit of the 99% confidence interval

Confidence interval for the population mean: Use of the t..
Suppose that a random sample of twenty recently sold houses in a certain city has a mean sales price of S$300,000, with a standard deviation of $7000. Under
the assumption that house prices are normally distributed, find a 99% confidence interval for the mean sales price of all houses in this community. Then find the
lower limit and upper limit of the 99% confidence interval.
Carry your intermediate computations to at least three decimal places. Round your answers to the nearest whole number. (If necessary, consult a list of
formulas.)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
