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.

step-by-step explanation:

i dont get

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
