A simple random sample of 60 items resulted in a sample mean of
97. The population standard deviation is 16.
1. Based on the information in Scenario 8.1, you wish to compute
the 95% confidence interval for the population mean, that is [
Lower limit , Upper limit ]. In the above calculation the value of
the Lower limit is? (to 1 decimal)
2. Based on the information in Scenario 8.1, you wish to compute
the 95% confidence interval for the population mean, that is [
Lower limit , Upper limit ]. In the above calculation the value of
the Upper limit is? (to 1 decimal)
3. Based on the information in Scenario 8.1, you wish to compute
the 95% confidence interval for the population mean, that is [Lower
limit , Upper limit ]. However, now assume that the same sample
mean was obtained from a sample of 120 items, n = 120. Given this
new information, the calculation of the value of the Lower limit
is? (to 2 decimal)
