(Round all intermediate calculations to at least 4 decimal places.) Consider the following hypotheses: H 0 : = 290 H A : 290 The population

(Round all intermediate calculations to at least 4 decimal places.)

Consider the following hypotheses:

H₀:= 290

H_A: 290

The population is normally distributed with a population standard deviation of 71. UseTable 1.

a.Use a 5% level of significance to determine the critical value(s) of the test.(Round your answer to 2 decimal places.)

Critical value(s)

b-1.Calculate the value of the test statistic with= 300 andn= 85.(Round your answer to 2 decimal places.)

Test statistic

b-2.What is the conclusion at= 0.05?RejectH₀since the value of the test statistic is greater than the critical value.RejectH₀since the value of the test statistic is smaller than the critical value.Do not rejectH₀since the value of the test statistic is greater than the critical value.Do not rejectH₀since the value of the test statistic is smaller than the critical value.

c.Use a 1% level of significance to determine the critical value(s) of the test.(Round your answer to 2 decimal places.)

Critical value(s)

d-1.Calculate the value of the test statistic with= 255 andn= 85.(Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.)

Test statistic
