A student believes that the average grade on the statistics final examination is 87. A sample of 36 final examinations is taken.
The average grade in the sample is 83.96 with a sample standard deviation of 12. Carry out the hypothesis testing that the real mean is less than 87. Use a 0.05 level of significance.
Yes because 1.92/16 and 2.88/24 are both .12 which means 1 fluid ounce is 12 cents. 32 and 56 are the next sizes up because 3.84/.12 is 32 and 6.72/.12 is 56
