Based on the information given for each of the following studies, decide whether to reject the null hypothesis. For each, give (a) the Z-score cutoff (or cutoffs) on the comparison distribution at which the null hypothesis should be rejected, (b) the Z score on the comparison distribution for the sample score, and (c) your conclusion. Assume that all populations are normally distributed.1. Study A, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; one-tail test with high predicted.2. Study B, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; two-tail test.3. Study C, population mean = 10; population standard dev = 2; Sample score = 14; p < .01; one-tail test with high predicted.4. Study D, population mean = 10; population standard dev = 2; Sample score = 14; p < .01; two-tail.5. Study E, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; one-tail test with high predicted.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings

●yes, this statement is absolutely apt.

hope this you
