- Speeds of automobiles on a certain stretch of freeway at 11:00 PM are normally distributed with mean 65 mph. Twenty percent of the cars are traveling at speeds between 55 and 65 mph. What percentage of the cars are going faster than 75 mph?The distribution obtained by a simple process of successive addition of the entries in the frequency column. A. relative frequency B. cumulative frequency C. frequency D. cumulative percentageThe yield of a chemical process is being studied. From previous experience, yield is known to be normally distributed with σ = 3. The past five days of plant operation have resulted in the following percent yields: 91.6, 88.75, 90.8, 89.95, and 91.3. How large a sample is needed so that you would be 95% sure that the true mean is only off by less than 0.25 of the sample mean.
- Categorical and Frequency DistributionA sample is given from the values of the EV/Net Income index (an indicator that compares the value of an enterprise with its net profit) for 100 enterprises of this industry. 1. Make an interval variation series. 2.Plot a histogram of relative frequencies N.b) the first image is the table for the task and the second image(descriptive statistics), is describe the steps you should follow for the assignment.random sample of 16 subjects The ages were: Assuming that age is normally distributed in the population, can we conclude that the mean age of the population is less than 60 years? Let α = 0.05.
- .59. Potatoes. A high-quality product is one that is consistent and has very little variability in its characteristics. Controlling variability can be more difficult with agricultural products than with those that are manufactured. The following table gives the weights, in ounces, of the 25 potatoes sold in a 10-pound bag. (a) Summarize the data graphically and numerically. Give reasons for the methods you chose to use in your summaries. (b) Do you think that your numerical summaries do an effective job of describing these data? Why or why not? (c) There appear to be two distinct clusters of weights for these potatoes. Divide the sample into two subsamples based on the clustering. Give the mean and standard deviation for each subsample. Do you think that this way of summarizing these data is better than a numerical summary that uses all the data as a single sample? Give a reason for your answer.The age of children in kindergarten on the first day of school is uniformly distributed between 4.88 and 5.94 years old.
