Consider the following hypotheses:

H0: μ = 1,800
HA: μ ≠ 1,800

The population is normally distributed with a population standard deviation of 440. 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.)

c. x−x− = 1,650; n = 32 (Click to select)  Reject H0  Do not reject H0
d. x−x− = 1,700; n = 32 (Click to select)  Reject H0  Do not reject H0
