Answer:

P=3T-50

Step-by-step explanation:

Form the given four values we can assume a linear relationship between profit and the no of tickets sold.

Let the equation corresponding to that be some P=aT+b.

Now substitute the first set of values(100,50) in the above equation we get

100=50a+b.

Now substituting second set of values (100,250) we get 250=100a+b.

Let these equations be eq1 and eq2.

Now substract eq1 from eq2 we get 50a=150 or a=3.

Substitite value of a in one of the equations we get b=-50.

∴P=3T-50

coldgirl [10]

Answer:

Note: The full question is attached as picture below

a) Hо : p = 0.71

Ha : p ≠ 0.71

<em>p </em>= x / n

<em>p </em>= 91/110

<em>p </em>= 0.83.

1 - Pо = 1 - 0.71 = 0.29.

b) Test statistic = z

= <em>p </em>- Pо / [√Pо * (1 - Pо ) / n]

= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]

= 0.12 / 0.043265

= 2.77360453

Test statistic = 2.77

c) P-value

P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028

P-value = 0.0056

∝ = 0.01

P-value < ∝

Reject the null hypothesis.  There is sufficient evidence to support the researchers claim at the 1% significance level.
