Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)
Answer: 90% confidence interval would be (66.92,69.08).
Step-by-step explanation:
Since we have given that
Number of kittens = n = 35
Mean = 68 days
Standard deviation = 3.9 days
We need to find the 90% confidence interval.
So, z= 1.645
So, intervals would be

Hence, 90% confidence interval would be (66.92,69.08).
Answer: if you have infinity points, which i will asume are the events, they cant have the same probability because then the probability will not be normalized, because in graph of prob vs variable, you will se infinite area under the curve if the probability is constant.
And yes, can all points have positive probability of occurring, but besides you medium value (the bell for example) you will see an asintotic decrease to the zero.
