You are testing a claim and incorrectly use the normal sampling distribution instead of the t-sampling distribution. Does this

Keith_Richards [23]

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.

The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to

Morgarella [4.7K]

Answer:

9 mph

Step-by-step explanation:

Let he speed of the boat on the lake is x.

<u>Considering the speed of the current it will take him:</u>

22.5/(x + 6) + 22.5/(x - 6) = 9
2.5 / (x + 6) + 2.5 / (x - 6) = 1
2.5(x - 6 + x + 6) = (x + 6)(x - 6)
2.5*2x = x² - 36
x² - 5x - 36 = 0
x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
