Stat crunch In a study of 810810 randomly selected medical malpractice lawsuits, it was found that 496496 of them were dropped or dismissed. Use a 0.010.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Which of the following is the hypothesis test to be? conducted?

A. Upper H 0 : p less than 0.5
Upper H 1 : p equals 0.5

B. Upper H 0 : p greater than 0.5
Upper H 1 : p equals 0.5

C. Upper H 0 : p equals 0.5
Upper H 1 : p not equals 0.5

D. Upper H 0 : p equals 0.5
Upper H 1 : p less than 0.5

E. Upper H 0 : p not equals 0.5
Upper H 1 : p equals 0.5

F. Upper H 0 : p equals 0.5
Upper H 1 : p greater than 0.5

a) There is enough evidence that most medical malpractice lawsuits are dropped or dismissed.

b) F. Upper H 0 : p equals 0.5

Upper H 1 : p greater than 0.5

Step-by-step explanation:

If the claim is that most (more than half) medical malpractice lawsuits are dropped or dismissed, the null and alternative hypothesis are:

The sample mean is:

The standard deviation is estimated as:

The statistic is calculated as:

The P-value of this statistic is P=0.000, so the effect is significant.

The null hypothesis is rejected.

There is enough evidence that most medical malpractice lawsuits are dropped or dismissed.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

answer: its the third option.
