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

Solve the equation: 9 - 7 — 29 Select one: oz = 36 o -4 о - - 4 2

MArishka [77]

9x-7= 29

9x-7+7= 29+7

9x= 36

Divide by 9 for 9x and 36

9x/9= 36/9

x= 4

Check answer by using substitution method

9x-7= 29

9(4)-7=29

36-7= 29

29= 29

Answer is x=4 (second choice)

Is 4 + 15x = 49 true? How do you know?

jekas [21]

Answer:

Yes it is true.

Step-by-step explanation:

If you go on and solve for x, you get 3. I got this by subtracting the 4 from both sides, then getting 15x=45. Then I divided both sides by 15 and got x=3. If you plug that in, you get 4+45=49. This proves to be true.
