We will now derive the probability that a given observation is part of a bootstrap sample. suppose that we obtain a bootstrap sample from a set of n observations.

a. what is the probability that the first bootstrap observation is not the j^th observation from the original sample? justify your answer.

b. what is the probability that the second bootstrap observation is not the j^th observation from the original sample?

c. argue that the probability that the j^th observation is not in the bootstrap sample is (1 - 1/n)^n.

d. when n = 5, what is the probability that the j^th observation is in the bootstrap sample?

e. when n = 100, what is the probability that the j^th observation is in the bootstrap sample?

answer: -1

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
