- Chi-Square testarrow_forwardthe Mothersarrow_forwardChi-square There are 4 TV sets at the student center of a large university lounge. At a particular time of each day, four different soap operas (namely 1, 2, 3 and 4) are being transmitted at these TV sets. The attending number of students viewing the 4 soap operas are 80, 88, 79 and 53. The percentage of audience captured by these shows during one semester after the summer break are 25%, 30%, 25% and 20%, respectively. The survey consists of 300 students. a) if the viewing pattern has not changed, what number of students is expected to watch each soap opera? b)using descriptive statistics, show the relative frequency of students watching each soap opera before the break c)test at 1% significance level, if these numbers indicate a change in watching behaviour.arrow_forward
- A sample of 30 movies, an Excel .XLSX file of data is attached. Use the data contained to answer all parts of this question. The Movie column provides the name of the movie. The Year column provides the year the movies was released The Budget column provides the amount of money spent (in Millions of dollars) to film the movie The Domestic Gross($M) column provides the amount of money (in Millions of dollars) a movie made within the United States of America Answer each of the following questions. You will need to use technology. Test the claim that there is a correlation between the explanatory variable, budget, and the response variable, Domestic Gross, at the 5% significance level.

- Seating Capacity Determine the seating capacity of an auditorium with 36 rows of seats when there are 15 seats in the first row, 18 seats in the second row, 21 seats in the third row, and so on.arrow_forwardBroadway The ordered pairs below give the starting year and gross ticket sales S (in millions of dollars) for each Broadway season in New York City from 1997 through 2014. 1997,558 2003,771 2009,1020 1998,588 2004,769 2010,1081 1999,603 2005,862 2011,1139 2000,666 2006,939 2012,1139 2001,643 2007,938 2013,1269 2002,721 2008,943 2014,1365 (a) Use a graphing utility to create a scatter plot of the data. Let t=7 represent 1997. (b) Use the regression feature of the graphing utility to find the equation of the least squares regression line that fits the data. (c) Use the graphing utility to graph the scatter plot you created in part (a) and the model you found in part (b) in the same viewing window. How closely does the model represent the data? (d) Use the model to predict the gross ticket sales during the season starting in 2021. (e) Interpret the meaning of the slope of the linear model in the context of the problem.arrow_forwardPhysiology In a physiology class, a student must dissect three different specimens.
