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.
Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean, 
= 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have
The test statistic is -1.50
-2/3 ÷ 1/3
=(-2 × 3) / (1 × 3)
= -6/3
= -2/1
<span>= -2</span>
Answer: $270
Step-by-step explanation: Because 40% of 270 is 108
