Refer to the previous problem. How large a sample would be required to estimate the population proportion to within .05 with 95 percent confidence (.30 is the best available estimate of p): (a) If the finite population correction can be ignored? (b) If the finite population correction is not ignored and N= 1500? Please without Minitab or Rstudio, Step by step

1. How large of a sample is required if we want to estimate the mean price of a five year old Corvette within +/- $500 with 90% confidence if the standard deviation is known to be $3100. 2. Several factors are involved when creating confidence intervals, such as sample size, the level of confidence and margin of error. Which of the following statements are true. a. For a given sample size, reducing the margin of error will mean lower confidence....

An interval estimate of a population mean is required. The statistician is concerned that the sample may not have arisen from a Normal distribution as there was a distinct lack of symmetry in a boxplot of the ( continuous) variable of interest. List two approaches that could be used here to address this concern.
