Hello your question is incomplete attached below is the complete question
answer : 1596 ± 2.861
------ ( A )
Step-by-step explanation:
I will use excel function to resolve this question
<u>Determine the 99% confidence of interval for the difference in mean number of steps by all people</u>
∝ = 0.01
critical value ( t ) = 2.861 ( = TINV ( 0.01, 19 )
Given that :
S1 = 1580
S2 = 2350
n1 = 20
n2 = 20
Difference in mean = x1 - x2 = 1596
Margin of Error = t *
∴ 99% confidence of interval
= 1596 ± 2.861
------
