Question

the ampon when they are separung (getting on a plane) or do they walk laster when they are A reputable researcher measured the walking speed of random travelers in two International Air Tized in the table at different speeds depending on whether they are departing or arriving at the a=0.05 level of to view the findings e mean speed of people departing and H2 represent the mean speed of people arriving alternative hypothesis * Walking Speed 35 Direction of Travel Departure Arrival Mean speed 259 268 -alue for the (feet per minute) Standard deviation 54 und to three (feet per minute) Sample size act conclusio ect Ho The that travelers walk at Print Done peeds depe There is so U. TOVORO Sigma reverters walk at different spending on whether they are arriving or departing There is not sufficient evidence at the a=0.05 level of significance to say that travelers walk at different yur answer(s). e here to search 0 BLM @ e 9 W

Answer 1

null hypothesis: Alternate Hypothesis: # C Arrival Departure 259.000 268.0000 X2 54.000 30.0000 S1 35.000 35.0000 n2 Point estimate =x1-x2 -9.000 degree of freedom v = min(n1,n2)-1 34.0000 for 0.05 level with two tailed test and n-1 degree of freedom, critical value of t reject Ho if absolute value of test statistic t|>2.032 2.032 Decision rule: std error of difference v(s/n+s/n) 10.442 test stat t (X-X2-A)/Se -0.862 p value 0.395 O

from above:

for hypothesis: option B is correct

p value =0.395

for conclusion: option A is correct
