Question
Please help with questions A-D. C. What is the standard Deviation D. If the sample were increased to 80, how would your answer to parts a-c change? For part A the shape of the distribution would (be normally distributed, skewed right, or skewed left )? For part B the mean of the sampling distribution would (remain as or change to)? For part C the standard deviation of the sampling would (remain as or change to)?
