How many computers? In a simple random sample of 155 households, the sample mean number of personal computers was 2.7. Assume the population standard deviation is a=0.23. Part 1 of 4 (a) Construct a 95% confidence interval for the mean number of personal computers. Round the answer to at least two decimal places. A 95% confidence interval for the mean number of personal computers is 2.66<μ< 2.74 Part: 1/4 Part 2 of 4 (b) If the sample size were 135 rather than 155, would the margin of error be larger or smaller than the result in part (a)?
