Zahra is a company specializing in high-end cosmetics. Its signature nail polish color is Soft Lilac. One day, the inventory manager took a sample of 63 bottles of nail polish at the company's factory. She found that 12 of those bottles were Soft Lilac. On that day, 7 out of every 26 bottles of nail polish in the factory were Soft Lilac. For the inventory manager's sample, find and write with proper notation the sample proportion and population proportion of bottles that were Soft Lilac. Write the proportions as decimals (not percentages) rounded to two decimal places. (a) Sample proportion: (Choose one) (b) Population proportion: (Choose one) ▼

A random sample of 30 colleges from Kiplinger's list of the best values in private college provided the data shown in the file BestPrivateColleges (Kiplinger website). The variable Admit Rate () shows the percentage of students that applied to the college and were admitted, and the variable -yr Grad. Rate () shows the percentage of students that were admitted and graduated in four years. Click on the datafile logo to reference the data. b. Compute the sample correlation coefficient. Round your answer to two decimal places and enter negative value as negative number, if necessary. answer b please

uppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 13 adult male fitness center members from the membership database and then selects 13 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 1 male ?1 ?1=13 ?⎯⎯⎯1=132.5 ?1=45.3 2 female ?2 ?2=13 ?⎯⎯⎯2=108.7 ?2=31.1   df=21.256 The population standard deviations are unknown and unlikely to be equal, based on the sample data. Laura plans to use the two-sample ?-procedures to estimate the…

The Ladies Professional Golfers Association (LPGA) maintains statistics on performanceand earnings for members of the LPGA Tour. Year-end performance statistics for 134 golfersfor 2014 appear in the file named 2014LPGAStats3 (LPGA website, April 2015). Earnings($1000s) is the total earnings in thousands of dollars; Scoring Avg. is the average score for allevents; Greens in Reg. is the percentage of time a player is able to hit the greens in regulation;Putting Avg. is the average number of putts taken on greens hit in regulation; and Drive Accuracy is the percentage of times a tee shot comes to rest in the fairway. A green is considered hitin regulation if any part of the ball is touching the putting surface and the difference betweenthe value of par for the hole and the number of strokes taken to hit the green is at least 2.a. Develop an estimated regression equation that can be used to predict the average scorefor all events given the average number of putts taken on greens hit in…
