They found that there was a peak in breakups on Valentine’s Day and Mondays with a dip on Christmas Day. [Source: McCandless, D. (July 2010). The beauty of data visualization. TEDGlobal talks.] Suppose you are a researcher. You conduct a hypothesis test to determine whether the mean number of breakups on Wednesdays is greater than the mean number of daily breakups. Assume that the mean number of daily breakups is 10.3 breakups (the population mean). You obtain a sample of 10,000 Facebook status updates, which yields a sample mean of M = 11.4 breakups. Let μ denote the mean number of breakups on Wednesdays. Formulate your null and alternative hypotheses by selecting the appropriate values in the blue dropdown menus that follow.Estimate sensitivity, specificity, positive predictive value, negative predictive value and prevalence from data in the 2 x 2 table for an infectious disease and its diagnostic test.

As you review the data, you ask yourself, Assuming both teams handled roughly the same number of customers, which chart impresses me more? Which team is the most consistent? Which team, over time, has better average scores? Growing scores? Declining scores? What does the Descriptive Statistics ToolPak tell me about the data? Which team is showing improvement? Can I estimate (or visually predict using the best fit line) which team will have better future performance? If so, which team?

- What is the claim, evidence and reasoning?-In statistics, the percentage is the same or equivalent to the proportion (p). Percent means per 100. For example, if there are 1,000 residents in a town, and 60% are Democrats, then, on average, 60 out of each 100 are Democrats. You determine the total number of Democrats by converting the percentage to a proportion, .60, and multiplying .60 x 1,000, which equals 600. -To determine a percentage, we divide the part by the whole and multiply by 100. So, if 8 out of 234 seniors are reported to have tried Meth, we calculate the percentage: 8/234 0.0342 and multiply 0.0342 x 100= 3.42%. -Remember: when you multiply by 10, move the decimal point one place to the right3; when you multiply by 100, move the decimal point two places to the right, etc. Answer the questions that follow the Table below Adolescents at three drug treatment centers were surveyed. The questionnaire used consisted of 102 questions and was divided into four sections. The third section asked about past drug use. The…[STATISTICS] How do you solve this?
