Assume, for the sake of this question, that the data were collected through a well-designed, well-implemented random sampling me

amid [387]

Answer:

Since the pvalue of the test is 0.2743 > 0.1, the threshold probably was met.

Step-by-step explanation:

The widget manufacturing company had established a threshold of 60% preferring the proposed new widget to move forward with producing the new widgets.

This means that at the null hypothesis we test if the proportion is at least 60%, that is:

$H_{0}: p \geq 0.6$

And the alternate hypothesis is:

$H_{a}: p < 0.6$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

0.6 is tested at the null hypothesis:

This means that:

$\mu = 0.6$

$\sigma = \sqrt{0.6*0.4}$

Three hundred thirty-eight of 575 respondents reported preferring the proposed new widget.

This means that $n = 575, X = \frac{338}{575} = 0.5878$

Value of the test-statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{0.5878 - 0.6}{\frac{\sqrt{0.6*0.4}}{\sqrt{575}}}$

$z = -0.6$

Pvalue of the test and decision:

We want to find the probability of a proportion of 0.5878 or lower, which is the pvalue of z = -0.6.

Looking at the z-table, z = -0.6 has a pvalue of 0.2743.

Since 0.2743 > 0.1, the threshold probably was met.

for these scenarios, write equations or inequalities that reflect the relationship. The minimum number of hours required to rent

IgorLugansk [536]

Answer:

$100 + 35x \geq 280$ is the inequality that reflect the relationship.

Step-by-step explanation:

Given:

Charge for rental = $100

Additional charge = $ 35

Minimum amount that can be spent = $280

To Find:

equations or inequalities that reflect the relationship = ?

Solution:

Let x be the minimum number of hours

then the charge will be

100 + (number of hours)(additional cost per hour)

That is

100 + 35x

Now the minimum charge amount is $280 So, The charge can be 280 or more than 280

$100 + 35x \geq 280$

Jared bought a Suzuki 1000 for $12,698. If it depreciates at a rate of 11% per year, how much will it be worth in 3 years

Serga [27]

Original price = P = $12,698
Depreciation rate = r = 11% = 0.11
Time in years = t = 3
New price = A

The formula used will be:

$A=P(1-r)^{t}$

Using the values, we get:

$A=12698(1-0.11)^{3}=8951.70$

Thus, the worth of Suzuki after 3 years will be $8951.70
