Hello your question is incomplete attached below is the complete question

answer : 1596 ± 2.861 $\sqrt{\frac{1580^2 }{20 } +\frac{2350^2 }{20 } }$ ------ ( 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 * $\sqrt{\frac{S^2_{1} }{n_{1} } +\frac{s^2_{2} }{n_{2} } }$

∴ 99% confidence of interval

= 1596 ± 2.861 $\sqrt{\frac{1580^2 }{20 } +\frac{2350^2 }{20 } }$ ------
