Some sample statistics are given below, where the difference is the number of cars on the 6th minus the number of cars on the 13dh Due in 6 hours, 38 minutes. vue FI UTTETT20T8 TU59 pm s, researchers in the UK collected data on t 6th 13th Diff 128,385 126,550 1,835 s 7,259 7,664 1,176 n 10 10 10 0] 10] Conduct a hypothesis test for evaluating whether the number of people out on Friday the 6th is different than the number of people out on Friday the 13th. Calculate the test statistic Find the p-value greater than 0.200 between 0.100 and 0.200 between 0.050 and 0.100 between 0.020 and 0.050 between 0.010 and 0.020 less than 0.010

Explanation / Answer

The statistical software output for this problem is:

One sample T summary hypothesis test:
? : Mean of population
H0 : ? = 0
HA : ? ? 0

Hypothesis test results:

Hence,

Test statistic = 4.934

p - Value is less than 0.010

Mean Sample Mean Std. Err. DF T-Stat P-value ? 1835 371.88385 9 4.9343363 0.0008
