Listed below are the measured radiation emissions corresponding to various cell phones models. Use the data to calculate the range and standard deviation. Then answer the following question, If one of each model of cell phone is measured for radiation and the results are used to find the standard deviation (which is what you just did), is that standard deviation equal to the standard deviation of the population of all cell phones that are in use? Why or why not? 0.38  0.55  1.54  1.55  0.50  0.60  0.92  0.96  1.00  0.86  1.46 PLEASE SHOW ALL WORK!!!

Heights for group of people normally distributed with mean = 63 inches and standard deviation = 2.6 inches. Find the height, h such that about 10% of people in the group are shorter than that height. (Round the answer to the nearest tenth.)h = in.What is the percentile, p ranking for that height? p = % You may need to use the appropriate table in the Appendix of Tables to answer this question.

The frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates. Use the frequency distribution to approximate the population mean and population standard deviation. Compare these results to the actual mean u = $1.481 and standard deviation a = $0.971. E Click the icon to view the frequency distribution for the tax rates. The population mean is S. (Round to three decimal places as needed.) Frequency distribution cigarette tax rates - X The population standard deviation is S (Round to three decimal places as needed.)

In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were: Inches of Rain 1 2 3 4 5 6 Frequency 1 2 8 2 1 1 The mean (¯xx¯) rain intensity:  inches (Please show your answer to 1 decimal place.)The median rain intensity:  inchesThe mode rain intensity:  inches (Please separate your answers by ',' in the bimodal situation. Enter DNE if there is no mode or if there are more than two modes.)

Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. ... The indicated IQ score is. (Round to the nearest whole number as needed.) X 5 0.3204

Using your favorite statistics software package, you generate a scatter plot that displays a linear form. You find a regression equation and the standard deviation for both variables. The standard deviation for x is 1.12, and the standard deviation for y is 4.12. The regression equation is reported as y=-4.7 +1.41x  What fraction of the variation in y can be explained by the variation in the values of x? (Enter your answer as a decimal between 0 and 1.)

Using your favorite statistics software package, you generate a scatter plot which displays a linear form. You find a regression equation and the standard deviation for both variables. The standard deviation for x is 2.03, and the standard deviation for y is 5.2. The regression equation is reported as - 5.5 + 1.84x What fraction of the variation in y can be explained by the variation in the values of x? (Enter your answer as a decimal between 0 and 1.)

A normal population has mean u = 50 and standard deviation o = 5. What is the 80th percentile of the population? Use the TI-84 Plus calculator. Round the answer to at least one decimal place.

Augusta National Golf Course. Earlier in this section, we found that the population standard deviation of the lengths of the holes at the Augusta National Golf Club is 132.0 yd. In this context, is the number 132.0 a parameter or a statistic? Explain your answer.
