1kg=1,000g\\1g=1,000mg\\\\therefore\\1kg=1,000\times1,000mg=1,000,000mg\to1mg=\frac{1}{1,000,000}kg\\\\2,000,000mg=\frac{2,000,000}{1,000,000}kg=\boxed{2kg}

Answer:

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 } } ------
