Question

Suppose you use simple random sampling to select and measure 47 dogs' weights, and find they have a mean weight of 57 ounces. Assume the population standard deviation is 2.9 ounces. Based on this, construct a 99% confidence interval for the true population mean dog weight. Give your answers as decimals, to two places ounces

Step 1

The standard error is calculated by dividing the standard deviation by the square root of the sample size. In this case, the standard deviation is 2.9 ounces and the sample size is 47. Standard Error (SE) = Standard Deviation / sqrt(Sample Size) SE = 2.9 / Show more…
