Answer:
yes
Step-by-step explanation:
Answer: the number of roses sold is 69 while number of tulips is 37
Step-by-step explanation:
Let x represent the number of roses that the flower shop sold.
Let y represent the number of tulips that the flower shop sold.
The number of roses sold was 5 less than twice the number of tulips sold. This means that
x = 2y - 5 - - -- -- - - - - - ;1
If the shop sold 106 flowers in total, it means that
x + y = 106
Substituting x = 106 - y into equation 1, it becomes
106 - y = 2y - 5
3y = 106 + 5 = 111
y = 111/3 = 37
x = 106 - y = 106 - 37
x = 69

linear
Step-by-step explanation:
Answer:
(A) When the sample size increases, both α and β may decrease.
Step-by-step explanation:
Which of the following is correct?
(A) This option is right.
When a sample's size increases, the values for alpha and beta may decrease; if and only if sample size is the denominator in the slope equation (in each case) and the numerator stays the same (that is, ceteris paribus; all other things being equal). The larger the denominator, the smaller the slope value for alpha and beta.
(B) This option is wrong
Type 2 error can only occur when you fail to reject a true H0
(C) This option is wrong
Type 1 error can only occur if or when you don't reject a false H0
(D) This option is wrong
The level of significance is the probability of a Type 1 error, not the probability of a Type 2 error.
