How many computers? In a simple random sample of 195 households, the sample mean number of personal computers was 1.48. Assume the population standard deviation is a 0.8. Part 1 of 4 (a) Construct a 90% confidence interval for the mean number of personal computers. Round the answer to at least two decimal places. A 90% confidence interval for the mean number of personal computers is 1.3858 << 1.5742 Part: 1/4 Part 2 of 4 (b) If the sample size were 235 rather than 195, would the margin of error be larger or smaller than the result in part (a)? Explain. The margin of error would be (Choose one) since (Choose one) in the sample size will (Choose one) the standard error. F
