Medical Malpractice Lawsuits The claim is that the majority

Medical Malpractice Lawsuits The claim is that the majority of medical malpractice lawsuits are dropped or dismissed, and a random sample of 500 lawsuits includes 349 that were dropped or dismissed. The test statistic in a right-tailed test is z = 1.00. The test statistic in a left-tailed test is z = -2.00. The test statistic in a two tailed test is z = 1.96. The test statistic in a two tailed test is z = -0.50. With H_1: p > 0.333, the test statistic is z = 1.50. With H_1: p = 0.667, the test statistic is z = 2.05. With p = 1/4. the test statistic is z=+-1.75. With H_1: p

Solution

29-36 can be solved using a normal distribution table!
29) P [ Z > 1.00 ] = 1 - .84134 = 0.15866
30) P [ Z < -2.00] = .02275
31) Z = 1.96 and 2 tailed test i.e, P [ Z > 1.96] + P [ Z < -1.96] = 0.04999579

32) p [ z > 0.5 ] + p[ z < -.5] = 0.6170751

33) test stat = 1.5...p-value = 0.0668072 which is greater than the standard level of significance 0.05.

so, p = 0.333 .null hypothesis is true!

34) test stat = 2.05..p-value = 0.04036443..whoich is less than 0.05,.
so, H1 is true! p is not equal to 0.667!
35) z = -1.75..p-value = 0.0801183 > 0.05..so, accept H0..p = 1/4...

36) z = -0.45..p-value = 0.3263552..> 0.05..so accept H0..p = 2/3..

37) There is sufficient evidence to support the claim that the proportion of male golfers is indeed less than 0.5 !

38) There is sufficient evidence to support the claim that the percentage of female coaches is greater than 50%!

39) There is not sufficient evidence to support the claim that the proportion of red M&M\'s is different from 0.13..

40) There is sufficient evidence to support the claim that the proportion of smokers who experienced sleeping difficulty is equal to 0.34...
type 1 error = reject the fact that proportion of settled medical malpractice suits is 0.25 when it is true!
type 2 error = accept  that proportion of settled medical malpractice suits is 0.25 when it is false!
41) type 1 error = reject the fact that proportion of settled medical malpractice suits is 0.25 when it is true!
type 2 error = accept  that proportion of settled medical malpractice suits is 0.25 when it is false!

42) type 1 error = reject the fact that proportion of unlisted telephones in Nevada is 0.524 when it is true!
type 2 error = accept  that proportion of unlisted telephones in Nevada is 0.524 when it is false!

43) type 1 error = reject the fact that proportion of murders cleared by arrests is 0.62 when it is true!
type 2 error = accept  that proportion of murders cleared by arrests is 0.62 when it is false!

44) type 1 error = reject the fact that proportion of car crashes occuring less than a mile from home is 0.23 when it is true!
type 2 error = accept  that proportion of car crashes occuring less than a mile from home is 0.23 when it is false!...
