You may need to use the appropriate appendix table to answer this question. Alexa is the popular virtual assistant developed by Amazon. Alexa interacts with users using artificial intelligence and voice recognition. It can be used to perform daily tasks such as making to-do lists, reporting the news and weather, and interacting with other smart devices in the home. In 2018, the Amazon Alexa app was downloaded some 2,800 times per day from the Google Play store.† Assume that the number of downloads per day of the Amazon Alexa app is normally distributed with a mean of 2,800 and standard deviation of 860. (a) What is the probability there are 1,900 or fewer downloads of Amazon Alexa in a day? (Round your answer to four decimal places.) (b) What is the probability there are between 1,600 and 2,400 downloads of Amazon Alexa in a day? (Round your answer to four decimal places.) (c) What is the probability there are more than 2,900 downloads of Amazon Alexa in a day? (Round…
Laura is a human resources director for a manufacturing plant. She has become concerned with the number of safety violations that have been reported by supervisors. She decides to start a safety seminar that all employees will need to attend. Using her computer, she creates a spreadsheet that will track the number of violations over the next six months as all employees attend the seminar. The x-axis will represent the number of employees who have completed the seminar and the y-axis will represent the number of safety violations reported. The spreadsheet will automatically create a scatterplot with a line of best fit. What does she hope to see as she implements her plan? O a positive correlation, indicating safety improvement O a negative correlation, indicating safety improvement O no correlation, indicating safety improvement O a curving line that starts out as a positive correlation and turns negative to indicate safety improvement

A researcher believed that the number of rental cars in service by a car rental company would have an impact on the total annual revenue for that car rental company. Five small car rental companies were surveyed, with the number of Cars in service recorded in units of 1000 (so if a car rental company had 54000 cars in service, a 54 would be recorded) and Annual Revenue measured in millions of dollars (so an Annual Revenue of $10,000,000 would be recorded as 10). The data follows: Cars (1,000s) Annual Revenue ($ millions)11.5 118 10.0 135 9.0 100 5.5 37 3.3 32 Part of the Excel-generated Simple Linear Regression output is provided below: ANOVA df SS MS F Significance F Regression 1 7891.863897 7891.863897 22.91180151 0.017339231 Residual 3 1033.336103 344.4453677 Total 4 8925.2 Coefficients Standard Error t Stat P-value Intercept -19.12490108 23.1658578…

A group of 110 people, who lived at varying distances (in kilometers) from the 3 kilometer island nuclear power station, were asked if they thought a full evacuation of the area was required, when it went critical. The researches wanted to know if the opinion to evacuate or not depended on how far from the reactor people lived. The people were divided into 5 categories, based on the distance to the power station. Each person was given 3 choices: evacuation was needed, evacuation was not needed, they did not care about it. Evacuation needed x x x x -.. .-. --. Evacuation not needed X x x X X Do not care X x x X ... You are doing a Chi Square test for independence. Compute the degrees of freedom for this test.
