A real estate agency says that the mean home sales price in City A is the same as in City B. The mean home sales price for 20 homes in City A is $127,450. Assume the population standard deviation is $25,877. The mean home sales price for 20 homes in City B is $112,277. Assume the population standard deviation is $27,112. At a = 0.01, is there enough evidence to reject the agency's claim? Complete parts (a) through (d) below. O B. The mean home sales price in City A is greater than as in City B. O C. The mean home sales price in City A is less than in City B. O D. The mean home sales price in City A is not the same as in City B. Let City A be sample 1 and let City B be sample 2.

Ocean currents are important in studies of climate change, as well as ecology studies of dispersal of plankton. Drift bottles are used to study ocean currents in the Pacific near Hawaii, the Solomon Islands, New Guinea, and other islands. Let x represent the number of days to recovery of a drift bottle after release and y represent The distance from point of release to point of recovery in km/100. The following data a representative of one study using drift bottles to study ocean currents. x day 72 79 32 96 203 y km/100 14.8 19.6 5.3 11.8 35.1 Σx=482 Σy=86.6 Σx2=62874 Σy2=2002.54 Σxy=11041.7 r=.93787 use a 1% level of significance to test the claim p>0.(use 2 decimal places) t=critical t= Se=4.4913 a=1.4966 b=.1641 D) find the predicted distance (km/100) when a drift bottle has been floating for 80 days.(use 2 decimal places) find a 90% confidence interval for your prediction of part D.

The numbers of polio cases in the world are shown in the table for various years. Year Number of Polio Cases (thousands) 1988 1992 1996 2000 2005 2007 350 138 33 3 3.2 1.3 Let f(t) be the number of polio cases (in thousands) t years after 1980. Copy the data to Desmos to draw a scatterplot of the data. Make sure to adjust the years so they represent years after 1980. a) Is it better to model the data with a linear or with an exponential model? [Select an answer b) Use regression in Desmos to find an appropriate model for f. Make sure to check Log mode in the parameter window in Desmos if you are fitting an exponential model. f(t) Round the coefficients to 4 decimal places. Hint: Use the variablet from the drop down menu when entering the equation. Do not just type in t. c) Predict the number of polio cases in 2013. d) Find the approximate half-life of the number of polio cases. Round the answer to one decimal place. years

Evan is investigating how long his phone's battery lasts (in hours) for various brightness levels (on a scale of 0-100). His data is displayed in the table and graph below. Brightness Level (x) 17 26 30 35 36 37 45 94 Hours (y) 6.7 5.9 5.8 4.5 6.8 6.1 3.8 2.1 10203040506070809010011012345678910-1Brightness LevelHours a) Find the equation for the line of best fit. Keep at least 4 decimals for each parameter in the equation. b) Interpret the slope in context. Evan should expect -0.0604 hours per brightness level. Evan should expect -0.0604 brightness level per hour. c) What does the equation predict for the number of hours the phone will last at a brightness level of 36? hours
