The average weight of new-born babies in the country of early generations used to be 115 ounces. A researcher suspected that this new generation of babies has on average become heavier. Is her suspicion supported by the data? Conduct the test at the 5% significance level 1. Specify the population parameter of interest (2 points) 2. Specify the null and alternative hypotheses (5 points) 3. Calculate the test statistics (5 points) 4. State the critical value and your decision rule (4 points) 5. Draw your conclusion (4 points) Note: All intermediate calculations must be reported to at least 4 decimal places before performing the final calculation.

If you receive a message in the Chrome download bar about the file not being commonly downloaded, please click the 'up-arrow' and select 'Keep.] In this data set, there is information of birth weights (in ounces) of 501 babies (Y) in Country A and the number of cigarettes smoked per day by their mothers during pregnancy (X). The average weight of new-born babies in the country of early generations used to be 115 ounces. A researcher suspected that this new generation of babies has on average become heavier. Is her suspicion supported by the data? Conduct the test at the 5% significance level 1. Specify the population parameter of interest (2 points) 2. Specify the null and alternative hypotheses (5 points) 3. Calculate the test statistics (5 points) 4. State the critical value and your decision rule (4 points) 5. Draw your conclusion (4 points) Note: All intermediate calculations must be reported to at least 4 decimal places before performing the final calculation.
