is this in my own words? the othter 1 screwed up?

We Answered:

It's OK yet u could try 2 change the structure of your writing to turn it into sumthing more... original.
i mean if u change it tat way,it would seem tat u DID refer 2 an external source but u rephrased it in ur own words. That reasoning shud keep ur teacher happy.

i hope it helpd.

Any comments ?

We Answered:

21 people is not a large enough sample to support your conclusion. Also you would help your case by stating how you were able to make your sample truly random.

someone help me solve for the Hypothesis testing ?

We Answered:

ANSWER: For signficance level ? = 0.01, NULL HYPOTHESIS H0: p = 0.002 (0.2% CANCER RATE) is accepted. CANCER RATE is constant.

Why??

POPULATION PROPORTION HYPOTHESIS TESTING, NORMAL DISTRIBUTION, 7-Step Procedure

1. PARAMETER OF INTEREST: p = POPULATION PROPORTION INCIDENCES OF CANCER

2. HYPOTHESES :
NULL HYPOTHESIS H0: p = 0.002 (0.2%: 572500/285000000)
ALTERNATIVE HYPOTHESIS H1: p ? 0.002

3. COMPUTATION OF POPULATION PARAMETER: STANDARD DEVIATION
? = sqrt[ p * ( 1 - p) / n ]
n = sample size [572500]
? = sqrt [0.02 * (1 - 0.0)/572500] = 0.00005918

4. COMPUTATION OF TEST STATISTIC ("critical value of z")
z = (p_hat - p) / ?
p_hat = SAMPLE PROPORTION [0.00198] (563710/285000000)
z = (0.00198-0.002)/ 0.00005918 = (approx.) -0.52

Valid when both conditions true:
n * p > 10 [572500 *0.002 = 1150 > 10] TRUE
n (1 ? p) > 10 [572500 * (1 - 0.002) = 571350 > 10] TRUE

5. "P-value" "Look-up" value of Normal Distribution "area under the curve" "to the left" of z = -0.52 is "P-value" = 0.30

6. TEST of P-value
P-value > ? (significance level) [0.30 > 0.01]; Cannot reject NULL HYPOTHESIS.
"When P-value is low, let it go" (let go the NULL HYPOTHESIS) P-value ? ?
"When P-value is high, let it fly" (let fly the NULL HYPOTHESIS) P-value > ?

7. CONCLUSION:
For signficance level ? = 0.01, NULL HYPOTHESIS H0: p = 0.002 (0.2% CANCER RATE) is accepted. CANCER RATE is constant.

Dispute letter to credit bureau?

We Answered:

This has been my experience, take from it what you need.
When I've had something on my credit report that should not have been there I write the credit bureau with proof that I'm me and tell them that account does not belong to me, that I don't know where it came from, I don't know if someone is using my name or if it just got mixed with my account in error or what and I ask them to "investigate" it. It takes them a while and they investigate, they tell me who turned in that item to them or where they copied it from (usually it's an error on their part as somebody missed a line when reading it off of some court report in the newspaper). Anyway they provide the name and address of the submitter and the purpose of the loan or bill. If they don't provide a name you can have the library look it up but you "must" direct your letter to someone specifically. Then I write a letter to that place and send it certified mail return receipt and tell them I have no idea why they put that on my account because it doesn't belong to me, and that I don't know where or how someone picked up the incorrect information and that they NEED TO provide proof that I owe it. Some time passes and they send the information. Clearly you can read whether it belongs to you or not, whether you have a clue as to who might have used your account, or whatever. Now take the data sent to you and re-write the credit bureau and reject that bill and ask the credit reporting agency to remove it and send you an updated copy of your credit report. Then wait to see what they do. usually they remove it. So you're fine for a while. But then in a few months send them $15 (or whatever their new fee is) and ask for an updated record. If it's still on there or on there again you need to re-rebut that. You don't have to be good at letter writing, just state the facts, even state exactly what I wrote.

I would suggest you write those on individual letters but you can put them all in the same envelope an envelope for each of the credit reports.
