Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

M = \frac{a+b}{2}

The standard deviation is:

S = \sqrt{\frac{(b-a)^{2}}{12}}

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5

Standard deviation:

S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Answer:

Carla's suitcase was a better purchase.

Step-by-step explanation:

The complete question is:

Carla and Daniel bought identical suitcases at different stores. Carla's suitcase originally cost $75 and was discounted 19% Daniel's suitcase original cost $85 and was on sale for 20% off the original price. Which suitcase was the cheaper?

Solution:

Cost Price of Carla's suitcase = $75

       Discount% for Carla = 19%

       The amount paid by Carla is,

       

       So, the amount paid by Carla was, $60.75.

Cost Price of Jeana's suitcase = $85

       Discount% for Jeana = 20%

       The amount paid by Jeana is,

       

       So, the amount paid by Jeana was, $68.

Carla's suitcase was a better purchase.

3. The academic Quiz advisor needs to choose the top member to compete in a final challenge. Tobin and Yolanda have approximatel
Natali [406]

Answer:

The safer option, would be to pick Yolanda, because of the lower risk involved. It is certain that she would score in and around the mean.

But, if one is a betting man, the rewards from Tobin performing to the favourable side of his wider range of possible scores would guarantee a higher mark. Although, there's an equal likelihood that Tobin's scores might tilt towards the unfavourable side.

Step-by-step explanation:

The mean absolute deviation (MAD) and the inter quartile range (IQR) both serve to highlight the spread variables in the dataset about the mean.

The higher their respective values, the more the variation of the variables in the dataset. It means

A high MAD and IQR indicate that the possible different obtainable scores from the candidate can take on values from extreme lows to extreme highs all around the mean, a wider range of possible scores.

This translates to the fact that Tobin's scores, which have a clearly superior MAD and IQR, have a higher risk attached to them. It is possible the scores in the exam take on values much lower than the mean or values much higher than the mean.

Yolanda on the other hand, has a lower MAD and IQR, thereby indicating a narrower range of possible values for her scores. This means that her scores will hover in and around the mean without big variations.

Yolanda's scores have a lower risk attached to them as it is guaranteed thay she would score close to their common mean score.

But Tobin's scores have a high risk and high reward attached to them. Going with Tobin would mean that one is ready to expect a score from a wider range about the mean.

Tobin could spectacularly post scores that are very much more than their mean score or post scores that are way worse than their mean score.

So, the choice of who to pick depends on which approach one takes to this subject matter.

Minimum Highest loss would mean Yolanda is safer and a better option.

Maximim Highest gain would mean Tobin is worth the risk and might be a better option.

Hope this Helps!!!

Use the given level of confidence and sample data to construct a confidence interval for the population proportion p.
Molodets [167]

Answer:

The 95% confidence interval for the population proportion is (0.778, 0.884).

Step-by-step explanation:

We have to calculate a 95% confidence interval for the proportion.

The sample proportion is p=0.831.

 

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.831*0.169}{195}}\\\\\\ \sigma_p=\sqrt{0.00072}=0.027

The critical z-value for a 95% confidence interval is z=1.96.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=1.96 \cdot 0.027=0.053

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sisgma_p = 0.831-0.053=0.778\\\\UL=p+z \cdot \sisgma_p = 0.831+0.053=0.884

The 95% confidence interval for the population proportion is (0.778, 0.884).
