- We use statistics to describe events in the past or expectations about the future, and the financial calculator provides valuable shortcuts for performing various statistical calculations, such as means, standard deviations, and regression parameters. When calculating statistics from data, it is important to recognize when you are working with a population or a sample. In general, a means you are working with all possible outcomes/ realizations, while a Entering Statistical Data If you are entering one variable list, type each value and press E+.

- Most Australian youth-sports leagues separate athletes by birthdate, and the cutoff date is January 1st. Thus, those children born in January and February have some physical advantages in youth sports over those born in November and December. A recent studysuggests that those physical advantages enjoyed early in life impact the likelihood of a child becoming a professional athlete. The table gives the number of Australian-born 2009 Australian Football League players born in different months of the year, as well as the proportion of births expected if the birthdates of the athletes matched the distribution of all births nationally. Is there evidence that the distribution of birthdates of AFL athletes is not the same as the distribution of birthdates nationally? Birthdates nationally in Australia and for Australian football players Proportion Actual for Months Nationally AFL players Jan-Mar 0.248 196 Apr-June 0.251 162 Jul-Sep 0.254 137…Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical Saturday, the oil change facility will perform 40 oil changes between 10 AM and 12PM. Treating this as a random sample, there would be a 10% chance of the mean oil change time being at or below what value.1. Assume that IQ are normally distributed with a mean of 100 and standarddeviation of 18. For a sample of 15 adults, find the probability that their mean IQscore will be greater than 94?
- Suppose that the value of stock varies each day from $14 to $25 with a uniform distribution. Find quartile 1Based on predictive modeling, this upcoming Winter is going to have very unpredictable weather. The National Weather service is considering abolishing specific long-term forecasts, and instead will utilize a statistical model that predicts a mean of six significant snowfalls per month. Use this information to answer the following question correctly: Trying to be forward-thinking, I'm going to try planning my one month long Winter Break based around this model's predictions. I will only travel for the holidays if there is at most one significant snowfall over winter break. What is the probability of this happening? O 0.0174 O 0.0149 O 0.0025 O 0.05421. The expected completion time of a project is 22 weeks and a project standard deviation of 2.1 weeks. the best estimate of the probability of completing the project within 21 days is
- Tony B. is attempting to start a landscaping business. He estimates that to break even, he will need about 150 customers. He believes that he will lose approximately $500 per customer for each customer fewer than the 150. At the moment, he believes there is an 80% probability that he will be able to secure between 130 and 170 customers, and that there is a 50/50 chance that demand will be greater than 160 customers. What is the mean or expected number of sales? Need to know how to calculate?Español A r.able indicator of a baby's health is the weight gained in the fir year of the baby's life. Assume that the population of all such weight gains for baby boys is approximately normally distributed. A study claimed that the mean of this population is 3.454 kg. As a practicing pediatrician, you want to test this claim. So, you select a random sample of baby boys, and you record the weight each gained in their first year. Follow the steps below to construct a 95% confidence interval for the population mean of all the weight gains for baby boys in their first year. Then state whether the confidence interval you construct contradicts the study's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Take Sample Sample size: 0 Point estimate: 0 Sample standard deviation: 0 Critical value: 0 Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you…Cody took his first physics exam and scored an 80. The population mean for this exam is 70, and the standard deviation is 5. What is the probability of selecting a person with a score greater than Cody’s?
