Answer:
95% confidence for µ, the average number of times a horse races
(12.493 , 18.107)
Step-by-step explanation:
<u>Explanation</u>:-
The veterinarian finds that the average number of races a horse enters is 15.3
The mean of the sample x⁻ = 15.3
Given standard deviation of the sample 'S' = 6.8
Given sample size 'n' = 25
Degrees of freedom = n-1 =25-1 =24
The tabulated value 't' = 2.064 at two tailed test 0.95 level of significance
<u> 95% confidence for µ, the average number of times a horse races</u>
<u></u>
<u></u>
<u></u>
<u></u>
(15.3 - 2.80704 ,15.3 +2.80704)
(12.493 , 18.107)
<u>Conclusion</u>:-
95% confidence for µ, the average number of times a horse races
(12.493 , 18.107)
Subtract 59.99 from 64.19.
64.19 - 59.99 = 4.20
<u>The tax she paid was $4.20, so now we need to find the percentage.</u>
Divide 4.20 by 59.99.
4.20 ÷ 59.99 = 0.07
Multiply 0.07 by 100 to find the percentage.
0.07 × 100 = 7
<u>The sales tax in the area was 7%.</u>
