Step-by-step explanation:
The question isn’t popping up?!?
Answer:
(a)- Let the time in minutes of the phone call on mortality to parents be Tm and time in minutes of the phone call on dental pain be Td.
Null hypothesis:
Tm = Td
Alternate hypothesis:
Tm > Td
t-stat = (diff in means - 0)/std devn of diff in means
= -1.26
p-value = 0.74
(b)- Generic conclusion is donot reject null hypothesis as the p-value is greater than 0.05.There is no
difference in the means between the 2 groups.
(c)- In the context of the problem, the conclusion is there is no difference in preference for mortality or dental pain related calls.
When the actual thing is people want to talk when thinking on mortality, but the predicted is there is no difference.
Then we are committing a type Il error (falsely retaining the null hypothesis). prediction is stating
that the null hypothesis is true (there is no difference) but indeed there is difference. This is false retention or false negative.
