A researcher is interested in estimating the mean length of walleye in a lake with a 95% confidence interval. Assuming the standard deviation of lengths is inches, estimate the sample size required so that margin of error does not exceed 3 inches.
Saturated mixture of water at 1500kPa is throttled to 100kPa and 150 degree C in a steam line. Calculate the temperature and quality of the water at the inlet.
Assume the population standard deviation is 2.1 pounds. b. Physician thinks that the margin of error is too large. Estimate the sample size required to estimate the mean birth weight within 0.3 pounds with a 98% confidence interval.
