Hassan used the iterative process to locate StartRoot 0.15 EndRoot on the number line. A number line going from 0 to 0.9 in incr

ements of 0.1. A point is between 0.4 and 0.5. Which best describes Hassan’s estimation? Hassan is correct because StartRoot 0.15 EndRoot almost-equals 0.4 Hassan is correct because the point is on the middle of the number line. Hassan is incorrect because StartRoot 0.15 EndRoot is less than 0.4. Hassan is incorrect because the point should be located between 0.1 and 0.2.

Answer:

Hassan is incorrect because StartRoot 0.15 EndRoot is less than 0.4

Step-by-step explanation:

√0.15 < √0.16 = √0.4² = 0.4

Correct option is:

  • Hassan is incorrect because StartRoot 0.15 EndRoot is less than 0.4

21% of deaths among male adults can be attributed to heart diseases. Is this percentage different among residents in Sonoma Coun
qwelly [4]

Answer:

Step-by-step explanation:

The null hypothesis is usually the default statement while the alternative hypothesis is its opposite and usually tested against the null hypothesis.

In this case study, the null hypothesis is u = 21%/0.21, the percentage is not different among residents in Sonoma County and is equal to 0.21.

While the alternative hypothesis is u =/ 0.21, the percentage is different among residents in Sonoma County; not equal to 0.21

We have that
x²<span>-20x
</span><span>Group terms that contain the same variable
</span>(x²-20x)
Complete the square 
(x²-20x+10²)------> (x-10)²

the answer is
the number must be 100

A manufacturer produces light bulbs that have a mean life of at least 500 hours when the production process is working properly.
denpristay [2]

Answer:

We conclude that the population mean light bulb life is at least 500 hours at the significance level of 0.01.

Step-by-step explanation:

We are given that a manufacturer produces light bulbs that have a mean life of at least 500 hours when the production process is working properly. The population standard deviation is 50 hours and the light bulb life is normally distributed.

You select a sample of 100 light bulbs and find mean bulb life is 490 hours.

Let \mu = <u><em>population mean light bulb life.</em></u>

So, Null Hypothesis, H_0 : \mu \geq 500 hours      {means that the population mean light bulb life is at least 500 hours}

Alternate Hypothesis, H_A : \mu < 500 hours     {means that the population mean light bulb life is below 500 hours}

The test statistics that would be used here <u>One-sample z test statistics</u> as we know about the population standard deviation;

                           T.S. =  \frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }  ~ N(0,1)

where, \bar X = sample mean bulb life = 490 hours

           σ = population standard deviation = 50 hours

           n = sample of light bulbs = 100

So, <u><em>the test statistics</em></u>  =  \frac{490-500}{\frac{50}{\sqrt{100} } }

                                     =  -2

The value of z test statistics is -2.

<u>Now, at 0.01 significance level the z table gives critical value of -2.33 for left-tailed test.</u>

Since our test statistic is higher than the critical value of z as -2 > -2.33, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which <u>we fail to reject our null hypothesis.</u>

Therefore, we conclude that the population mean light bulb life is at least 500 hours.
