Use the t-distribution and the given sample results to complete the test of the given hypotheses. assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal. test vs using the fact that the treatment group (t) has a sample mean of 8.6 with a standard deviation of 4.1 while the control group (c) has a sample mean of 11.2 with a standard deviation of 3.4. both groups have 25 cases.(a) give the test statistic and the p-value.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
