Answer:
With the information given in the question, the blank spaces are filled thus:
Step-by-step explanation:
1. The intercept is the estimated amount of a purchase, if time spent viewing the online catalog was zero minutes.
2. The slope coefficient is the estimate of amount that a purchase charges/changes, for one extra minute spent viewing the online catalog.
3. The proportion of total variation in purchases that can be explained by variation in the minutes spent viewing an online catalog is equal to the coefficient of determination.
4. The p-value is the probability value
5. Reject the null hypothesis if there is sufficient evidence to support the claim that the regression slope coefficient is not equal to zero.
NOTE: In the case of number 5, the assumption is that;
Null Hypothesis: The regression slope coefficient = 0
Alternative Hypothesis: The regression slope coefficient ≠ 0
Other answers require numerical information and full data, in order to be computed or calculated.
Math pls help
Answer:
y=2/3x+600
Step-by-step explanation:
as x goes up by 3, y goes up by 2. So this means the slope is 2/3. also, you add 600 which is the y intercept

Answer:
14.6% probability that a randomly chosen person will test positive
Step-by-step explanation:
We have these following probabilities:
10% probability that a randomly selected person has the disease.
If a person has the disease, 92% probability of testing positive.
100-10 = 90% probability that a person does not have the disease.
If a person does not have the disease, 100-94 = 6% probability of testing positive.
What is the probability that a randomly chosen person will test positive
92% of 10% or 6% of 90%.
Then
p = 0.92*0.1 + 0.06*0.9 = 0.146
14.6% probability that a randomly chosen person will test positive
Given: An urn contains 11 balls, 3 white, 3 red, and 5 blue balls.
You win $1 for each red ball you select and lose a $1 for each white ball you select.
Let X be the number of times you win.
The total number of ways to select 2 balls (order does not matter) =
The number of ways so that two balls are white (and
The number of ways so that two balls are red (and
The number of ways so that one ball is red, one is white (and
The number of ways so that two balls are blue (and ):
i.e.
The number of ways so that one ball is blue, one is white (and ):
The number of ways so that one ball is blue, one is red (and ):
Thus, the probability mass function (p.m.f.) of X would be ( in attachment) :
