Question

#1 part A.) To test H0​: μ=100 versus H1​: μ≠100, a random sample of size n=20 is obtained from a population that is known to be normally distributed. Complete parts​ (a) through​ (d) below.

(aa.) ​If x̅=104.4 and s=9.4, compute the test statistic.

t0 = __________

(bb.) If the researcher decides to test this hypothesis at the α=0.01 level of​ significance, determine the critical​ value(s). Although technology or a​ t-distribution table can be used to find the critical​ value, in this problem use the​ a "t-distribution area in right tail" chart.

(cc.) Draw a​ t-distribution that depicts the critical region(s).

(dd. ) Will the researcher reject the null​ hypothesis?

#1 part B.) To test H0​: μ=20 versus H1​: μ,<20, a random sample of size n=19 is obtained from a population that is known to be normally distributed. Complete parts​ (a) through​ (d) below.

(aa) ​If x̅=18.3 and s=4.1, compute the test statistic.

t = __________

(bb) Draw a​ t-distribution with the area that represents the​ P-value shaded.

(cc) Approximate the​ P-value.

(dd) If the researcher decides to test this hypothesis at the α=0.05 level of​ significance, will the researcher reject the null​ hypothesis?

Answer 1

c.)

d.)

Test Statistic<Critical value, do not reject Null Hypothesis.

I have solved first four part and first complete question, second question is completely different , so please post agan
