The population mean is actually 47.94 , or about 48 . Compare this value to the point estimate and the confidence interval. There is something unusual about the data. Describe it and state how it would affect the confidence interval.

Step 1
The point estimate is typically the sample mean calculated from the data. Let's assume the point estimate is calculated to be, for example, 45. Show more…

Suppose the following data are selected randomly from a population of normally distributed values.45 51 43 48 43 57 54 39 42 48 45 39 44 Construct a 95% confidence interval to estimate the population mean.(Round the intermediate values to 2 decimal places. Round your answers to 2 decimal places.) ≤μ ≤ 2. A random sample of size 40 is taken from a population of 200 members. The sample mean is 64 and the population standard deviation is 9. Construct a 96% confidence interval to estimate the population mean. What is the point estimate of the population mean?(Round your answers to 2 decimal places.) ≤ μ ≤ The point estimate of the population mean is
