Answer: 78,000 units

Step-by-step explanation:

Equivalent units of production for conversion costs = Units completed and transferred out + Equivalent unit of ending units

Units completed and transferred out = Units started - Ending units

= 90,000 - 20,000

= 70,000 units

Equivalent unit of ending units = 20,000 * 40%

= 8,000 units

Equivalent units of production for conversion costs = 70,000 + 8,000

= 78,000 units

Fail to reject the null hypothesis.

Step-by-step explanation:

Here we have to perform a hypothesis test on the difference of proportions. We may want to answer if there is significant difference in the proportions of male and females.

The null and alternative hypothesis are:

$H_0: \pi_1=\pi_2\\\\H_1: \pi_1\neq\pi_2$

The significance level is defined as 0.05.

The YES proportion for females is:

$p_1=33/98=0.337$

The YES proportion for males is:

$p_2=30/102=0.294$

The weighted average of p can be calculated as:

$p=\frac{n_1*p_1+n_2*p_2}{n_1+n_2}=\frac{33+30}{98+102}=0.315$

With this p, we estimate the standard deviation

$s=\sqrt{\frac{p(1-p)}{n_1}+\frac{p(1-p)}{n_2} }=\sqrt{\frac{0.315(1-0.315)}{98}+\frac{0.315(1-0.315)}{102} }=0.066$

The test statistic z can be calculated as:

$z=\frac{p_1-p_2}{s} =\frac{0.337-0.294}{0.066}=\frac{0.043}{0.066}=0.65$

We can calculate the p-value for z, taking into account is a two-sided test

$P(|z|>0.65)=0.52$

The P-value (0.52) is greater than the significance level (0.05), so the effect is not significant. It failed to reject the null hypothesis.

We have enough evidence to conclude that the proportions that vote YES are different between genres.

The additional set of values which could be included in the table is; (10,2).

<h3>Which additional set of values can be included in the table?</h3>

As evident in the task content, it follows that for a 15 unit increase in x, depth, there is a 3 unit increase in y, pressure.

On this note, it follows that with each 5 unit increase in x corresponds to 1 unit increase in y.

And ultimately, at x = 10, y = 2 × 1 = 2.

If point (4, 5) is on the graph of a function, which equation must be true?

olya-2409 [2.1K]

Answer: f(4) = 5

Step-by-step explanation:

If the point (4, 5) is on the graph of a function, this means that when you input 4 you get an output of 5.

Inputs are usually shown with the x-coordinate, and outputs are usually shown with the y-coordinate.

This means that (4, 5) is an input of 4 for an output of 5.
