(a)Based on the above data structure, we should use a (2-sample T test (pooled variance)/Paired T (Matched Pairs)Test/2-sample T test (unequal variance)/Leven's Test.)
(c)Carry out the appropriate statistical test and find the Test Statistic and P-value.
Test Statistic=(use three decimals)
Complete the interpretation and compute the Pvalue.
Assuming H0is (false/uncertain/true),the probability of (observing stronger evidence to support the rejecting the/failing to reject the/observing stronger evidence against the)null hypothesis is ___(use three decimals).
(d)Based on these samples, at the 5%level of significance, we can conclude that the (average/median/sample mean/standard deviation)completing time of the assignments in the busy cafe (significantly different/significantly similar/significantly higherot significantly higher/significantly lowerot significantly lower)than the (average/median/sample mean/standard deviation)completing time of the assignments in the quiet library.
(a) Based on the above data structure, we should use a ? (b) Let Xcafe denote the time it takes to complete each assignment in the cafe., and Xribrary be the time it takes to complete each assignment in the library. Choose the correct statistical hypotheses. A. Ho : Hcafe-library = 0, HA : Hcafe-library 0, HA : Hcafe-library Hlibrary O H. Ho : Hcafe-library = 0 HA : Pcafe-libraryStep by Step Solution
