- Identify the lower class limits, upper-class limits, class width, class midpoints, and class boundaries for the given frequency distribution. Also, identify the number of individuals included in the summary. (Type integers or decimals. Do not round. Use ascending order.)

Create a frequency distribution and a relative frequency distribution using 7 classes. a) Since data were collected for variable(s), the correct graph to make is a . b) Using the formula class width = (maxX - minX)/(number of classes) and rounding up to the next whole number, the class width is Complete the frequency/relative frequency table using 7 classes. Round relative frequencies to 3 decimal places.The graph illustrates the distribution of test scores taken by College Algebra students.

I am producing 400-gram loaf breads in one of my production lines and measured the weights of 28 loaf breads from the same batch as shown in table below. (*see attached image for the table.)A. Summarize data in a frequency distribution table using a 5-gram interval. B. Illustrate data in a frequency histogram using a 5-gram interval.C. Compute for relative frequency of 3rd interval and cumulative relative frequency of the 4th interval.A distribution of values is normal with a mean of 210 and a standard deviation of 20. From this distribution, you are drawing samples of size 32.Find the interval containing the middle-most 94% of sample means: Enter your answer using interval notation. In this context, either inclusive or exclusive intervals would be acceptable. Your numbers should be accurate to 1 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. I am confused because I don't understand interval notation.
- 2. Central limit theorem Imagine that you are doing an exhaustive study on the children in all of the preschools in your school district. You are particularly interested in how much time children spend with parents on weekdays. You find that for this population of 2,431 children, the average number of minutes spent with parents on weekdays is μ = 223.17, with a standard deviation of σ = 148.75. You select a random sample of 25 children of preschool age in this same school district. In this sample, you find that the average number of minutes the children spend with parents on weekdays is M = 245.49, with a standard deviation of s = 163.63. The difference between M and μ is due to the . Suppose you compile all possible samples of 25 children of preschool age in your school district. If you calculate the mean of each sample (M) and create a frequency distribution of these means, this distribution is referred to as the . The mean of this distribution, that…A study investigating the relationship between age and annual medical expenses randomly samples 100 individuals in a city. It is hoped that the sample will have a similar mean age as the entire population. If the standard deviation of the ages of all individuals in the city is σ = 20, find the probability that the mean age of the individuals sampled is within 1.5 years of the mean age for all individuals in the city. Do not round your answer. Hints: Find the sampling distribution of the sample mean age and use the central limit theorem. You don’t have to know the population mean to answer this, but if it makes it easier, use a value such as μ=35.Inclusions are defects in poured metal caused by contaminants. The number of (large) inclusions in cast iron follows a Poisson distribution with a rate of 3.4 per cubic millimetre. What is the probability of at least one inclusion in a cubic millimetre? Please enter the answer to 3 decimal places.
