A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 42 specimens and counts the number of seeds in each. Use her sample results (mean = 79.1, standard deviation = 10.3) to find the 95% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. 95% C.I. =

A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 73 specimens and counts the number of seeds in each. Use her sample results (mean = 66.5, standard deviation = 6.3) to find the 99% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. 99% C.I. =

A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 60 specimens and counts the number of seeds in each. Use her sample results (mean = 17.1, standard deviation = 16.4) to find the 95% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

only C. and D.
The average American consumes 95 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 11 randomly selected college students and found that they averaged 108.5 liters of alcohol consumed per year with a standard deviation of 18 liters. What can be concluded at the the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b. The null and...
