A random sample of 8 cigarettes of a certain brand has an average nicotine content of 4.2 milligrams and a standard deviation of 1.4 milligrams. Is this in line with the manufacturer’s claim that the average nicotine content does not exceed 3.5 mg? Use a 0.01 level of significance and assume the distribution of nicotine contents to be normal.

Answers

Answer:

0.0793 > 0.01, which means that we have a result in line with the manufacturer's claim.

Step-by-step explanation:

Manufacturer’s claim that the average nicotine content does not exceed 3.5 mg

This means that the null hypothesis is given by:

[tex]H_{0}: \mu = 3.5[/tex]

And the alternate hypothesis is:

[tex]H_{a}: \mu > 3.5[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

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

3.5 is tested at the null hypothesis

This means that [tex]\mu = 3.5[/tex]

A random sample of 8 cigarettes of a certain brand has an average nicotine content of 4.2 milligrams and a standard deviation of 1.4 milligrams.

This means that [tex]n = 8, X = 4.2, \sigma = 1.4[/tex]

Value of the z-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{4.2 - 3.5}{\frac{1.4}{\sqrt{8}}}[/tex]

[tex]z = 1.41[/tex]

Pvalue of the test:

We are testing if the mean is higher than 3.5.

The sample mean found is of 4.2, and we have to find the probability of finding a sample mean at least as large as this, which is 1 subtracted by the pvalue of z = 1.41.

z = 1.41 has a pvalue of 0.9207

1 - 0.9207 = 0.0793

0.0793 > 0.01, which means that we have a result in line with the manufacturer's claim.

Answers

Answer:

D) x = ± 2√5 - 4

Step-by-step explanation:

2x² + 16x - 8 = 0

Yah, i plugged this into m a t h w a y

(all of ur questions pretty much can use this app or website)

Answer:

D

Step-by-step explanation:

Given

2x² + 16x - 8 = 0 ( divide through by 2 )

x² + 8x - 4 = 0 ( add 4 to both sides )

x² + 8x = 4

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(4)x + 16 = 4 + 16

(x + 4)² = 20 ( take the square root of both sides )

x + 4 = ± [tex]\sqrt{20}[/tex] = ± [tex]\sqrt{4(5)}[/tex] = ± 2[tex]\sqrt{5}[/tex] ( subtract 4 from both sides )

x = - 4 ± 2[tex]\sqrt{5}[/tex] → D

A car journey is in two stages Stage1 the car travels 110 miles in 2 hours Stage 2 the car travels 44 miles at the same average speed as stage 1 Work out the time for stage 2 Give you answer in minutes.

Answers

9514 1404 393

Answer:

  48 minutes

Step-by-step explanation:

The average speed for stage 1 is ...

  speed = distance/time = (110 mi)/(2 h) = 55 mi/h

Then the time for stage 2 is ...

  time = distance/speed = (44 mi)/(55 mi/h) = (4/5 h)(60 min/h) = 48 min

The time for stage 2 is 48 minutes.

Answer:

Solution :-

We know that

SpeeD = Distance/Time

Speed = 110/2

Speed = 55 mi/hr

For, 2

Speed = 44/55

Speed = 4/5

Speed = 48 min

If $520 is borrowed for 290 days at 2.15% simple annual interest, how much will be repaid at the end of 290

Answers

Step-by-step explanation:

Formula for simple interest

where a = final amount

p = principal amount

r = annual interest rate

t = time in years

given p = 520,

r = 2.15/100

t = 290/365 (1 year = 365 days)

[tex]a = 520(1 + ( \frac{2.15}{100} )( \frac{290}{365} )) \\ = 520 (1 + \frac{1247}{73000} ) \\ = 520( \frac{74247}{73000} ) \\ = 528.88 \: (2.dp)[/tex]

To a set of five grades with an average of 7.31, the following grades are added 4.47 and 9.15 What is the new average?

Answers

Answer:

New mean average of 7 grades = 7.17 (Approx.)

Step-by-step explanation:

Given:

Mean average of 5 grades = 7.31

Number of grades = 5

New grades = 4.47 and 9.15

Find:

New mean average of 7 grades

Computation:

Total of old grades = Mean average of 5 grades x Number of grades

Total of old grades = 7.31 x 5

Total of old grades = 36.55

Total of new grades = Total of old grades + 4.47 + 9.15

Total of new grades = 36.55 + 4.47 + 9.15

Total of new grades = 50.17

New mean average of 7 grades = 50.17 / 7

New mean average of 7 grades = 7.167

New mean average of 7 grades = 7.17 (Approx.)

The parallel line will have the same slope.

If you rearrange the above equation, you find ...

  b = y - mx

For the given point and slope, the new y-intercept will be ...
