A television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If
Alinara [238K]

Answer:

Test statistic  z= 1.708

Step-by-step explanation:

given that a  television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If this is to happen, it will have to move one of its most viewed shows to another slot.

Sample size n = 827

Sample proportion p = \frac{438}{827} \\=0.5297

H_0: p =0.5\\H_a: p >0.5

(right tailed test)

This is because they would be interested if more than half viewers are ready for the change

Test statistic = Z = p difference/std error

p difference = 0.0297

Std error =\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.5*0.5}{827} } \\=0.0174

Z =1.708

p valu e= 0.9562

Since p >0.05 we fail to reject H0

Test statistic  z= 1.708
