Answer:

30 oranges

Step-by-step explanation:

Since 1/4 was subtracted from the total of 40 as apples, we would want to find the amount of oranges, or 3/4.

To find a fraction amount of a number, multiply that number by the decimal form of the fraction.

Since the decimal form of 3/4 is .75, all we have to do is multiply 40 by .75.

40*.75=30

There was 30 oranges.

Hope this helps!

nexus9112 [7]

Answer:

$z=\frac{0.40 -0.45}{\sqrt{\frac{0.45(1-0.45)}{370}}}=-1.933$

$p_v =2*P(z$

Step-by-step explanation:

Information given

n=370 represent the sample selected

$\hat p=0.4$ estimated proportion of readers owned a laptop

$p_o=0.45$ is the value that we want to test

z would represent the statistic

$p_v$ represent the p value

Creating the hypothesis

We need to conduct a hypothesis in order to test if the true proportion of readers owned a laptop is different from 0.45, the system of hypothesis are:

Null hypothesis: $p=0.45$
