Answer:
Monthly household expenditures on groceries
Step-by-step explanation:
The response variable is the one for which measurements are desired and that depends on other variables.
In this case, family size, household income, and household neighborhood are independent variables, while the response variable is the monthly household expenditures on groceries.
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
First $25,000: Commission = 1/100*25000 = $250
$25,001 to $95,000: Commission = 3/100*(95000-25000) = $2,100
Above $95,000: Commission = 5/100*(100000-95000) = $250
Total commission earned = 250+2100+250 = $2,600
Answer: 0.6915
Step-by-step explanation:
Given : 
Since , the distribution follows a Normal distribution.
The formula to calculate the z-score is given by :-
For x=
The p-value = 
Hence, the required probability : 0.6915
