A.0.39 grams
margin of error at 90% confidence intervals is
M.E = 0.39 grams
Step-by-step explanation:
<u>Explanation</u>:-
Given a sample of size n = 25
mean of the sample x⁻ = 15 grams
Standard deviation of the sample 'S' = 1.5 grams
<u>margin of error at 90% confidence intervals is determined by</u>
<u></u>
<u></u>
The degrees of freedom ν = n-1 = 25-1 =24
The tabulated value t₀.₉₀ = 1.318

Margin of error = 0.3954
<u>Conclusion</u>:-
Margin of error at 90% confidence intervals = 0.3954

Let's break it down.
You spent $20. Plus the $1 tip.
20 - 1 = 19
$19 is how much you spent without the tip
The cost for the taxi ride itself is $3
19 - 3 = 16
$16 is how much you spent without the ride cost + tip
You spent $2 for every mile traveled.
16/2=8
You traveled 8 miles
