The additional growth of plants in one week are recorded for 11 plants with a sample standard deviation of 4 inches and sample mean of 10 inches. t* at the 0.05 significance level = [Ex: 1.234 Margin of error = Ex: 1.234 Confidence interval = [ Ex: 12.345 Ex: 12.345 1 [smaller value, larger value]

The sample mean and standard deviation from a random sample of 32 observations from a normal population were computed asx =25 and s = 10. Calculate the t statistic of the test required to determine whether there is enough evidence to infer at the 8% significance level that the population mean is greater than 22.Test Statistic =

The average size of a farm in one county is 162 acres with a standard deviation of 38 acres. The average size of a farm in a second county is 182 acres with a standard deviation of 16 acres. Assume the data were obtained from two samples that had 30 farms each.  Can it be concluded that the average size of the farms in the two counties is different?  (Let α = 0.05)                              First , choose which hypothesis statements is correct.     T-stat =               Round to 2 decimal places. P-value =    Decision:          Type Retain Ho or Reject Ho

The additional growth of plants in one week are recorded for 6 plants with a sample standard deviation of 1 inches and sample mean of 12 inches. t∗ at the 0.10 significance level = Margin of error = Confidence interval = [                ,              ]                               [smaller value, larger value]
