Answer:
H0: μm − μw = 0
against the claim
Ha: μm − μw ≠ 0
Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.
Step-by-step explanation:
1) Let the null and alternate hypothesis be
H0: μm − μw = 0
against the claim
Ha: μm − μw ≠ 0
2) The significance level is set at 0.05
3) The critical region is z > + 1.96 and z< -1.96
4) The test statistic
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
Here p1= 411/ 1390= 0.2956 and p2= 213/753=0.2829
pc = 411+ 213/1390+753
pc=624/2143
pc= 0.2912
qc= 1-pc= 1-0.2912=0.7088
5) Calculations
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
z= 0.2956-0.2829/√ 0.2912*0.7088( 1/1390+ 1/753)
z= 0.0127/ √0.2064 (0.00204)
z= 0.0127/0.02056
z= 0.6177
6) Conclusion
Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.
The Solution:
Given:
Each withdrawal by Brandon = $x
ATM charge per transaction = $2
Required:
To find an expression for Brandon's total withdrawal if he withdraws the same amount once a week for 7 weeks.
Step 1:
We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.
Step 2:
Finding the required total amount, we have:
Therefore, the correct answers are: [options 2, 3, and 4]
I think it is A
i dont really know what it is i am gessing
The distributive property works like this:
a(b+c) = ab + ac
To split apart bigger numbers, you can change 45 into 40+5. Writing this using the distributive property looks like this:
6(40+5)
Now, like we did above with a, b, and c, you can rewrite it to this:
(6 x 40) + (6 x 5)
So, your answer is B.
sqrt(2/3) = 0.816496
since it is a decimal with no repeating numbers it would be irrational
