Answer:
From the given data, the typical appropriation is utilized rather than t distribution for testing. The thicknesses of the curve similarly influence both normal distribution and territory of t distribution. The normal distribution test and t test give a similar dismissal for the invalid theory for any tail of the test. Besides, the tests normal sampling distribution and t sampling distribution give a similar dismissal to null hypothesis.
Along these lines, the outcomes got by utilizing normal distribution and t distribution are distinguished as same and for each situation, the tail thickness doesn't influence the event of the basic qualities.
Eight thirds (also known as 8/3) is equivalent to two and two thirds (numerically written: 2 2/3). Explanation: to solve this, find out god many times 3 can fit into eight. Three can fit into eight 2 times (since 3*2 is 6), which leaves you with 2 left. Since this remainder of 2 can not be divided by 3, it is put into a fraction of 2/3. Therefore, the answer is 2 2/3.
