Consider the following hypothesis test H0: p ? 66% ; H1 : p > 66%. The significance level used for this test on the proportion of the population is: ?= 5%. A simple random sample of size n =500 from this population gives a proportion equal to 70%. Calculate the statistical value of the variable Z test (z-score) for rejecting or not H0 0.97 1.645 -1.888 1.95 1.888 1.94 -1.94

Consider the following hypotheses: H0: μ = 4,900, HA: μ ≠4,900. The population is normally distributed with a population standard deviation of 600. 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.)

Consider the following hypothesis test: H0: μ ≥ 20 Ha: μ < 20 A sample of 50 provided a sample mean of 19.4. The population standard deviation is 2. a. Compute the value of the test statistic (to 2 decimals). Enter negative value as negative number. -2.21 b. What is the p-value (to 3 decimals)? .014 c. Using α = 0.05, can it be concluded that the population mean is less than 20? Yes d. Using α = 0.05, what is the critical value for the test statistic (to 3 decimals)? Enter negative value as negative number. -1.645 State the rejection rule: Reject H0 if z is less than or equal to the critical value. Using α = 0.05, can it be concluded that the population mean is less than 20? Yes
