Testing to see if there is evidence that the proportion of US citizens who can name the capital city of Canada is greater than 0
klemol [59]

Answer:

b) B and D and c) A and C

Step-by-step explanation:

The hypotheses would be:

H_0: p =0.75\\H_a: p >0.75

(Right tailed test at 5% level)

Sample proportions are

Sample              A                 B                C                 D

Success            31               34               27               38

Proportion p     0.775         0.85            0.675          0.95

Std error

(sqrtpq/n)          0.066        0.056          0.074          0.034

p diff

p-0.75               0.025        0.10             - 0.075        0.20

Z stat                  

p diff/SE            0.0757       1.77                 1.01          5.80

p value               0.469       0.038             0.156       0.000001

we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.

b) Only B and D provide against the null.  Because p <0.05

c) A and C provide no evidence for the alternative because p >0.05
