A researcher is looking at the plant growth based on a soil supplement. She takes 5 plants and measures the plant height before she implements the supplement and after. The heights for time 1 and time 2 are shown below. The researcher would like to see if ' there is a difference in plant growth before and after the supplement at a .05 level of 1 signicance. Include the test statistic t in your conclusion and whether the researcher should reject or fail to reject the null hypothesis. Round values to 2 decimal places.

A runner is analyzing whether the amount of miles she can run has increased after joining a new training program. She records 6 running times before the training and 6 running times after the training and gathers a difference mean of 3 miles, with a standard deviation of 2. She analyzes this increase at a .05 level of significance. Include the test statistic t in your conclusion and whether the researcher should reject or fail to reject the null hypothesis. Round values to 2 decimal places. 5. Given XD=4, SD=10, n=25, with a level of significance of .05 and a two-tailed test, What is the 95% confidence interval?
