The histogram below shows the same data that are shown in one of the four boxplots. Given that the data has mean -2s, which boxplot goes with the histogram? Please justify your answer. 10 15253 35 . A population is normally distributed with a mean of 55 and a standard deviation of 4. Using the Empirical Rule, approximately what percentage of data values fall between 51 and 59? Please show your calculations. A 68% 1.15% с 95% D 99.7% You...
You are given the formula P(20 < x < 80) = 95% Does this formula represent (please justify your answer): A. the middle 95% of the standard normal distribution? B. the middle 95% of a normal distribution? C. the 95th percentile of a standard normal distribution? D. the 95th percentile of the normal distribution?
You are given the formula (P< x <80)=95% Does this formula represent please justify your answer You are given the formula . Does this formula represent (please justify your answer): the middle 95% of the standard normal distribution? the middle 95% of a normal distribution? the 95thpercentile of a standard normal distribution? the 95thpercentile of the normal distribution?
please help on both 1.) We learned in section 6.1 that the Empirical Rule (a.k.a 68-95-99.7 rule) is a good estimate of probability within a specific number of standard deviations from the mean for any normal distribution. We know that this rule only provides a good estimate and that it is not very precise. With use of the Normalcdf function in our calculator, we can find exact values. For example, when using the Empirical Rule 95% is expected to be...
Answer the following question involving "The Normal Distribution and the 68-95-99.7 Rule" and show how I got the answers below. Answers: 1)a) 68% b) 47.5% c) 2.5% 2) 12 or 13 people Questions: 1) A population of dogs have weights that are normally distributed with an average of 30 pounds with a standard deviation of 3 pounds. a) What percent of the dogs weigh between 27 and 33 pounds? b) What percent of the dogs weigh between 30 and 36...
1. Assuming age fits a normal distribution (it definitely does not!) with your mean and standard deviation. Note: The answers will seem ridiculous! (a) Draw the normal curve with the usual labels for the 68-95-99.7 rule. (b) 68% of students are between what two ages? (c) 95% of students are between what two ages? (d) 99.7% of students are between what two ages? (e) 50% of students are older than what age? (f) 34% of students are between what two...
Please answer the 4 circled questions for me.
Thank you.
2. Soybeans. Soybean yield in Iowa was historically low in 2012. Yield of soybeans (bushels per acre) in Iowa during 2012 can be described by a Normal distribution with a mean of 49 bushels per acre and a standard deviation of 7 bushels per acre. Use the 68-95-99.7 Rule (Empirical Rule) to answer the following questions. Note that answers based on the normal table rather than the empirical rule will...
if someone could give an explanation for D. the answer is 0.37%. I
would just like to know how they got that answer in steps.

Corn. The average yield of corn (bushels per acre) for Iowa counties during 2018 can be described by a Normal distribution with a mean of 192.6 bushels per acre and a standard deviation of 20.3 bushels per acre. Use the 68-95-99.7 Rule (Empirical Rule) to answer the following questions. (a) Create a well labeled normal curve for the average corn yield (bushels per acre) for Iowa counties during 2018. On this graph numerically label the mean (iv), the center 68%...
