A manufacturer of colored candies states that 13​% of the candies in a bag should be​ brown, 14​% ​yellow, 13​% red, 24​% ​blue,

20​% ​orange, and 16​% green. A student randomly selected a bag of colored candies. He counted the number of candies of each color and obtained the results shown in the table. Test whether the bag of colored candies follows the distribution stated above at the α=0.05
level of significance.


Color | Frequency | Claimed Proportion

Brown | 60 | 0.13

Yellow | 65 | 0.14

Red | 56 | 0.13

Blue | 63 | 0.24

Orange | 82 | 0.20

Green | 63 | 0.16

Answer:

The null and alternative hypotheses are:

H_{0}: The bag of colored candies follows the distribution stated

H_{a}: The bag of colored candies does not follow the distribution stated

Under the null hypothesis, the test statistic is:

\chi^{2} =\sum \frac{(O-E)^{2}}{O}

Where:

O is the observed frequencies

E is the expected frequencies

The calculation are done in the attachment

\therefore \chi^{2} =14.490

Now, we have to find the chi-square critical value at 0.05 significance level for df = n - 1 = 6 - 1 = 5. Using the chi-square table, we have:

\chi^{2}_{critical} = 11.070

Since, the chi-square test statistic is greater than chi-square critical value. Therefore, we reject the null hypothesis and conclude that the bag of colored candies does not follow the distribution stated.

Approximately 40% of the calls to an airline reservation phone line result in a reservation being made. (round to three decimal
IRISSAK [1]

Answer:

The probability that none of the 10 calls result in a reservation is 0.60%.  In turn, the probability that at least one call results in a reservation being made is 99.40%.

Step-by-step explanation:

Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:

0.6 ^ 10 = X

0.006 = X

0.006 x 100 = 0.60%

Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.

100 - 0.60 = 99.40

In turn, the probability that at least one call results in a reservation being made is 99.40%.

PLEASE HELP WILL GIVE BRAINLIEST.
kari74 [83]

Answer:

Choice D

Step-by-step explanation:

For this one I would find if the point lands on the line.

<em><u>Choice A:</u></em>

What we have to do is to plug in -4 for x and 4 for y.

y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2

The point is not on this line so this cannot be it.

<em><u>Choice B:</u></em>

We pug what we know again.

y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}

The point is not on this line so it can't be it.

<em><u>Choice C:</u></em>

We pug in what we know again.

y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21

The point is not on this line so it can't be it.

The next one has to be it, but we'll check it just in case.

<em><u>Choice D:</u></em>

We plug in what we know again.

y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4

The point is on this line so this is the line.
