If the data set contains 40 data values, approximately how many of the data values will fall within the range of 6.5 to 13.5?ДҐ000 students take an exam with a mean of 59 and a deviation of 8. The mean is 10 and the standard deviation is 3.5. If one starts assembling at 4 pm what is the probability that he will finish before the compДecide by calculation how many candidates out of a total of 1000 candidates for the position of CEO meet the eligibility requirements for the desired performance of this top management position with at least 67% probability - provided, of course, that the The assembly time for the toy follows a normal distribution with a mean of 75 minutes and a standard deviation of 9 minutes. Assuming a normal distribution, how many women ran faster than Joan? There were 415 women who ran in her age group. Joan's finishing time for the bolder boulder 10 km race was 1.77 standard deviations faster than the women for her age group. Is there evidence to show that this group ha A random sample of 50 students were given the same test and showed an average score of 83.20.

4 Access time for secondary datДЄ standardized test was administered to thousands of students with a mean score of 85 and a standard deviation of 8. 3 The most passive method of data collection is observation. The most frequent observation in a data set is known as the mode. Write TRUE OR FALSE for each question: 1 Standard deviation is a measure of central location. a) What is the probability that a randomly selected light bulb will have a lifespan of more than 320 hours? b) Up to what value of L hours can the

The lifetime of a light bulb is a random variable with a normal distribution of x = 300 hours, Пѓ = 35 hours. What are students in the bottom the 20% having what GPA? The average GPA is 2.78 with a standard deviation of 4.5. What the range in minutes 68% of the batteries will last? What is the range in minutes approximately 99.7% of batteries will last? Here are the links to the two activities that are overviewed, as well as the video which walks through the two main function needs in the activities.The life expectancy of batteries has a normal distribution with a mean of 350 minutes and standard deviation of 10 minutes. Great tool supporting students in this remote learning environment.

The video how-to that sort of goes along with these lessons is using the fx-115ESplus emulator software, which, if you check out the link below for the Casio Cares, is available as a free download with an extend free trial through August 31. The calculator here is used to here to help students find the area under the normal curve. The second activity is about representing data in various ways (dot plots, histograms, and box plots), and determining probability. In this activity, the calculator in this is a tool to verify student solutions to quadratic equations. The first activity focuses on solving linear equations and inequalities in one variable and quadratics. They are not вЂanswer giversвЂ™, but if used properly and appropriately, they help verify students work, they help them analyze mathematics and make decisions and these lessons do a nice job of making the calculator work with the student rather than do the work for the student. In fact, the calculator is just a tool to verify work or help in the analysis of a situation, which is what we should be doing with calculators. What I love about these activities is it isnвЂ™t all вЂusing the calculatorвЂ™.

The two lessons I am sharing are ones that utilize the two features I am highlighting. There is so much more that it can do, so consider this a teaser.

Today I am exploring just a tiny bit of the functionality that the Casio fx-115ESPlus2 scientific calculator has вЂ“ specifically, I am going to demonstrate how to use it to verify solutions and to determine probability of a normal cumulative distribution. But вЂ“ you really can do so much with just a scientific calculator, except graphing (though the fx-991EX does that too!). I think, like many, itвЂ™s assumed once you get into those higher mathematics courses, you need a graphing calculator. I am always amazed when I remember how much power a scientific calculator has to do high-school and upper level mathematics content.
