Question

Suppose that we wish to test a claim that there is a difference between the components of certain matched pairs, and that a simple random sample of these matched pairs was taken.

Answer each of the following questions

(a) The claim is is given by

A. β=0
B. ρ=0
C. r=0
D. G=0
E. x=y
F. n1=n2
G. The median of the differences ≠0
H. The data are in an order that is not random
I. The median of the differences =0
J. None of the above.

(b) The opposite of the claim is given by

A. n1≠n2
B. x≠y
C. ρ≠0
D. G≠0
E. Median ≠0
F. The data are in a random order
G. β≠0
H. The median of the differences ≠0
I. r≠0
J. The median of the differences =0
K. None of the above.

(c) If the differences between the components of the sample matched pairs yield to 16 positive signs, 19 negative signs and 3 zeros, then the test statistic is

A. x=16.
B. z=2.341498585142509.
C. x=−16.
D. z=13.
E. z=−2.341498585142509.
F. x=35.
G. x=3.
H. z=−1.341498585142509.
I. z=1.341498585142509.
J. z=+0.338061701891407.
K. z=−0.338061701891407.
L. x=19.
M. None of the above.

Answer 1

-: نعم Here a the c from the given daba apply hypothesis test erer (2). The claim is a 1. Has the median of the differences to - option (G) is correct. (b) the opposite of the claim given by Ho: The median of the differences=o. option (5) is correct (e) Here, 16+19+3338 =) The test statistic ano of (tve) is - 16 cs Scanned with 2 =16 option His correct CamScanner
