Complete question :
Two researchers, Jaime and Mariya, are each constructing confidence intervals for the proportion of a population who is left-handed. They find the point estimate is 0.13. Each independently constructed a confidence interval based on the point estimate, but Jaime’s interval has a lower bound of 0.097 and an upper bound of 0.163, while Mariya’s interval has a lower bound of 0.117 and an upper bound of 0.173. Which interval is wrong? Why?
Answer:
Mariya's interval
Step-by-step explanation:
Point estimate = 0.13
Mariya's confidence interval :
Lower boundary = 0.117
Upper boundary = 0.173
Jamie's confidence interval :
Lower boundary = 0.097
Upper boundary = 0.163
The correct confidence interval should have an average value equal to the value of the point estimate ;
Jamie's confidence interval average :
(0.097 + 0.163) / 2 = 0.26 / 2 = 0.13
Mariya's confidence interval average :
(0.117 + 0.173) / 2 = 0.29 / 2 = 0.145
Based on the confidence interval average obtained we can conclude that Mariya's interval is wrong as it the average obtained is greater than the point estimate.
0.145 > 0.13
Answer:
Line S
Step-by-step explanation:
Because Line R and Line S don't meet and dont intersect.
I hope this helps! I'm sorry if it's wrong.
Answer:
Step-by-step explanation:
We have been given that a skin care manufacture produces 85 g canister of skin balm. Any canister whose weight differs by more that 0.05 g cannot be shipped out.
To write an equation that would find the maximum weight of an acceptable canister (y) we will use an absolute value equation as the weight of an acceptable balm canister cannot be more than 85+0.05 and it cannot be less than 85-0.05.
This information can be expressed as 
.
Subtracting 85 from all the sides we will get,
Now using the definition of absolute value symbol we will get,
Therefore, the equation representing the maximum weight of an acceptable canister(y) is .
