ATQ: 28 = 11 + y
Answer:
option A
Step-by-step explanation:
Since All values in confidence interval are less than 3.12, we do not have sufficient evidence
as degree of freedom is sample size -1 ; hence df =20-1 =19
In construction of the confidence interval, a t-value with 19 degrees of freedom was used therefore option b, c and d are incorrect
also, In construction of the confidence interval, a z-value with 10 degrees of freedom was used
1. 60% can be written as 60/100, simplified as 3/5
2. 2/5 is 40/100, can be written as 40%
3. 1/3 is 33.33333...% -> 0.(3) [ infinite recurring decimals if i remember correctly]
4. 250 here is the base (original number)
5. 48/100 can be written as 48% -> 0.48
6. base
7. percentage
8. 300
9. 24%
10. portion
11. (i dont know what this mean, next time write it more carefully)
12. percentage
