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.
