Math 142 Chapter 10.3 Classwork 1) A marketing survey is conducted to study product recognition of a new smartwatch in two different cities. Of 558 New Yorkers surveyed, 193 knew the smartwatch while 196 out of 614 San Franciscans knew it. At 0.05 significance level, test the claim that the recognition rates are the same in both cities. a) Define populations and test parameters. Let population 1 corresponds to n1 =558 x1=193 PI = NY Let population 2 corresponds to 12= 6 14 x 2= 196 P2 = SF b) Write the claim, HO and Ha in symbolic form, find test statistic and p-value. Ho : P1= p2 Ha : P 1 7 P2 two tail test 2: 0. 9679 2 P valve: 0. 33305 51: 0. 05 c) Write the conclusion for HO and the conclusion for the claim. since pvalue 0. 3331 7 (0. 05 ), fail toreject Ho. since Ho is the claim there is notsufficent evidence to Narrant rejection of the claim that the d) What is the corresponding confidence interval? recognitionrates are 0 02774
