Using a significance level of 0.05 to compare results of treatment for carpal tunnel syndrome, test that the proportion for surgery is greater than the proportion for splints.

group Number of successes sample size

surgery 64 80

splints 56 80

Let denote the proportion for surgery and splints respectively.

There is sufficient evidence to support the claim that the proportion for surgery is greater than the proportion for splints.

Using a significance level of 0.05 to

a 45 year old woman recently underwent a carpal tunnel
release operation for carpal tunnel syndrome of the left hand
following the operation she complains of weakened flexion of the
thumb the tendon of which muscle have been damaged

To test the following hypotheses at the 0.05 level of
significance, using a sample size of
nequals=15.

Conduct a test at the a = 0.05 level of significance by
determining (a) the null and alternative hypotheses (b) the test
statistic (c) the critical value, and (d) the P-value. Assume that
the samples were obtained independently using simple random
sampling.
1. Test whether p1 is not equal to p2.
Sample data: x1 = 804, n1 = 874,
x2 = 902, n2 = 954

When treating carpal tunnel syndrome, should a patient be
treated with surgery or should a splint be applied? In a study on
this issue, 73 patients were treated with surgery and 83 were
treated with a splint. After 12 months, success was noted in 67
patients that had surgery, whereas success was noted in only 60 of
the patients that had a splint. Assume that the observations came
from a SRS.

Carpal tunnel syndrome is a common wrist complaint resulting
from a compressed nerve. It is often the result of extended use of
repetitive wrist movements, such as those associated with the use
of a keyboard. Among the various treatments available, two are
common: apply a splint or perform surgery. The splint treatment has
the advantages of being noninvasive. simpler, quicker, and much
less expensive. But do those advantages justify the splint
treatment instead of the surgery treatment? A critical factor...

Test the given claim using the α=0.05 significance level and
assuming that the populations are normally distributed and that the
population variances are equal.
Claim: The treatment population and the placebo population have the
same means.
Treatment group: n=9, x¯=110, s=5.9.
Placebo group: n=7, x¯=116,s=5.7.
The test statistic is =___________
The positive critical value is =__________
The negative critical value is =________
Is there sufficient evidence to warrant the rejection of the claim
that the treatment and placebo populations have...
