20 weeks

The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks

laila [671]

Hello!

As we can see, our first amount was 95 for the one machine. We are not multiplying it by anything from the second day as it was used the first. There is no 95 in B, and in C and D it is multiplied.

In A, we have a base of 95, plus 25 multiplied by x and y, and this fits the scenario perfectly. Our answer is A.

I hope this helps!

4.48 Same observation, difference sample size: Suppose you conduct a hypothesis test based on a sample where the sample size is

Lemur [1.5K]

Answer:

P-value is lesser in the case when n = 500.

Step-by-step explanation:

The formula for z-test statistic can be written as

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } } =\frac{(x-\mu)\sqrt{n}}{\sigma}$

here, μ = mean

σ= standard deviation, n= sample size, x= variable.

From the relation we can clearly observe that n is directly proportional to test statistic. Thus, as the value of n increases the corresponding test statistic value also increases.

We can also observe that as the test statistic's numerical value increases it is more likely to go into rejection region or in other words its P-value decreases.

Now, for first case when our n is 50 we will have a relatively low chance of accurately representing the population compared to the case when n= 500. Therefore, the P-value will be lesser in the case when n = 500.
