Answer:
Based on the result of his test , Thomas should fail to reject null hypothesis at a significance level of 0.01. Thomas sufficient evidence to conclude that the proportion of households without children in the set of all future samples reached by phone is not equal to the proportion of households without children in the population of all households.
Step-by-step explanation:
From the question we see that the p-value is greater than the level of significance (0.01 )so we fail to reject the null hypothesis.
This means that Thomas has sufficient evidence to conclude that the proportion of households without children in the set of all future samples reached by phone is not equal to the proportion of households without children in the population of all households.
She has decided on a strategy in which she will place four balls (marked A, B, C, and D) into a box.
She randomly selects one ball for each question and replaces the ball in the box.
The marking on the ball will determine her answer to the question.
There are five multiple choice questions on the exam.
What is the probability that she will get
a. Five questions correct?
b. At least four questions correct?
c. No questions correct?
d. No more than two questions correct?
Answer:
d no more than two questions correct
5a(y + 4) + 8(y + 4)
Answer:
Factoring the term we get
Step-by-step explanation:
We need to factor the term:
Factoring:
Taking (y+4) common
It cannot be further factored.
So, Factoring the term we get
-2.8760
-0.3477
0.7124
1.3738
Answer:
-0.34772
Step-by-step explanation:
One way of doing this problem is to change the base from 5 to 10.
Use the change of base formula:
log x
log x = ------------
5 log 5
so:
log (4/7) log 4 - log 7
log (4/7) = --------------- = ---------------------
5 log 5 log 5
Note that "log x" above is the common logarithm of x and is to the base 10.
Continuing, we get:
0.60206 - 0.84510 -0.24304
---------------------------- = --------------------- = -0.34772 (This corresponds to
0.69897 0.69897 the second given
answer choice.)
