Question

Consider the following hypotheses: H0: ? = 3,800 HA: ? ? 3,800 The population is normally distributed with a population standard deviation of 590. Compute the value of the test statistic and the resulting p-value for each of the following sample results. For each sample, determine if you can "reject/do not reject" the null hypothesis at the 10% significance level. (You may find it useful to reference the appropriate table: z table or t table) (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round "test statistic" values to 2 decimal places and "p-value" to 4 decimal places.) Test statistic p-value a. x? = 3,900; n = 130 Reject H0 b. x? = 3,900; n = 260 Reject H0 c. x? = 3,640; n = 36 Do not reject H0 d. x? = 3,720; n = 36 Do not reject H0

H0: ? = 3,800

Test statistic p-value
a. x? = 3,900; n = 130 Reject H0
b. x? = 3,900; n = 260 Reject H0
c. x? = 3,640; n = 36 Do not reject H0
d. x? = 3,720; n = 36 Do not reject H0
