p value and confidence interval
In a random sample of ten cans of corn from supplier B, the average weight per can of corn was sample mean or x bar = 9.4 ounces with standard deviation s = 1.8 ounces. Does this sample contain sufficient evidence to indicate the mean weight is less than 10 ounces? Use the p-value approach. Find a 98% confidence interval for population variance
Re: p value and confidence interval
"The data do not present sufficient evidence to indicate that the mean weight per can is less than 10 ounces..."
the confidence interval for 98% for population mean:
is it CI= 7.7943, 11.0057 OR CI= 8.2843, 10.5157???
