13.11 Random numbers. If you ask a computer to generate “random numbers" between 0and 5, you will get observations from a uniform distribution. Figure 13.12 shows the densitycurve for a uniform distribution. This curve takes the constant value 0.2 between 0 and 5 andis zero outside that range. Use this density curve to answer these questions.a. Why is the total area under the curve equal to 1?b. The curve is symmetric. What is the value of the mean and median?c. What percentage of the observations lie between 4 and 5?d. What percentage of the observations lie between 1.5 and 3?height = 0,20Moore/Notz, Statistics: Concepts and Controversies, 10e, 0 2020 W. H.

Figure 13.13 is a stemplot of the IQ scores that are consistent with the 2018article "Flynn effect and its reversal are both environmentally caused." This distribution isvery close to Normal with mean 100 and standard deviation 10. Use the Normal distributionwith mean 100 and standard deviation 10 as a description of the IQ test scores of all adults.Use this distribution and the 68-95–99.7 rule to answer Exercises 13.12 to 13.14.8 | 248 67789999 0001222455567788888899910000001111122344105555566677888991111022335566812 | 234Moore/Notz, Statistics: Concepts andControversies, 10e, © 2020 W.

andom numbers. If you ask a computer to generate "random numbers you will get observations from a uniform distribution. Figure 13.12 shows or a uniform distribution. This curve takes the constant value 0.2 betweer outside that range. Use this density curve to answer these questions. Vhy is the total area under the curve equal to 1? 'he curve is symmetric. What is the value of the mean and median? Vhat percentage of the observations lie between 4 and 5? Vhat percentage of the observations lie between 1.5 and 3? -height = 0.20

Please help thank you
Use the mean and standard deviation formula for a Uniform Distribution for our population distribution. Take the mean and standard deviation from your population distribution to find the mean and standard error of your sampling distribution. Don’t forget to label your axes and do not forget to write out your calculator command. Don’t forget the units on your percentile. Every statistic has the same units as your variable. All this information that is above goes with the image attached Please please answer everything please at least try to answer everything please I would really appreciate it thank you
