    c.
    d.

QUESTION 2

  1. A researcher selects a sample of 16 women and asks them to rate how important a sense of humor is in someone they want a long-term relationship with. She records scores averaging 1.6±0.8 (M±SD) on a rating scale from -3 (not important at all) to +3 (very important). Assuming that an average score of 0 is the null hypothesis, test whether or not women find this trait important at a .05 level of significance.

QUESTION 4

  1. Two researchers (A and B) compute a two-independent sample t test. For both tests, the standard error is the same, but the mean difference between the groups is larger for Researcher A. Which test is more likely to result in a decision to reject the null hypothesis?

QUESTION 9

  1. A researcher conducts two t tests. Test 1 is a one-tailed test with a smaller sample size at a .05 level of significance. Test 2 is a one-tailed test with a larger sample size at a .05 level of significance. What do you know about the critical values for each test?

jury assignment (A) – Top Premier Essays

i will provide example soon

THE CASE OF THE DRIVER WHO HAD ONE TOO MANY
Sam was insured under a life insurance contract policy that excluded death due to suicide. The policy had a face amount of $1 million. Two weeks after taking out the policy, Sam was driving home from his promotion party while intoxicated. He lost control of his car when a dog ran in the road and was killed when the car hit a utility pole. There was no one else involved in the accident. The weather was clear and the road was in good shape and well lighted. Sam’s insurance company refused to pay and Sam’s wife sued the company to force payment.
The Trial
Testimony at the trial proved conclusively that Sam was legally intoxicated when he left the party. There was also proof that there was nothing in the policy about lack of coverage in the event of an accident due to intoxication.m
The Arguments at Trial
The insurance company’s attorneys argued that benefit provisions apply only to death due to accidents – unintended and unavoidable mishaps – and that, although Sam appeared to have been in an accident, his death was due to his being intoxicated and therefore not an accident. They further argued that this concept was so logical that it did not need spelling out in the insurance policy. The estate’s attorneys argued that because the policy was silent about accidents due to intoxication, the benefit provision should apply regardless of the cause of the accident. The parties had a contract and all exclusions must be spelled out in the contract in order to be effective.
Questions to Discuss

Who do you think has the stronger argument, the insurance company or Sam’s estate? Why?
If you were the jury hearing this case, how would you decide? Why?
What do you think the rule regarding coverage of accidents due to use of drugs or excessive alcohol should be?
