- Q3. If the null hypothesis is not rejected when the null hypothesis is in error, what type of error, if any, has been made?3. According to an NDP Group report, the mean number of meals prepared and eaten at home is 700 per year. Suppose that a random sample of 36 households showed a sample mean number of meals prepared and eaten at home was 690. Assume o = 40. Test whether the population mean number of such meals is less than 700 using a significance level of 0.01.Which of the following are the appropriate null and alternative hypothesis? Η := 157, ΗΑ :# 157 Η : μ = 157, HA : μ 145 Η : μ = 157, HA : μ > 157 Η : μ = - 145, HA : μ < 145
- Assume that both populations are normally distributed. a) Test whether µ, # H, at the a = 0.01 level of significance for the given sample data. Sample 1 Sample 2 11 11 b) Construct a 99% confidence interval about u, - 42- 17.8 20.9 3.8 5.1Sample 1 Sample 2 Assume that both populations are normally distributed. a) Test whether u, >H, at the a = 0.01 level of significance for the given sample data. b) Construct a 99% confidence interval about u, - H2. 22 14 51.5 44.4 7.1 11.2 a) Perform a hypothesis test. Determine the null and alternative hypotheses.Is the statement Ho: 14 6 a valid null hypothesis? O No, equalities are not permitted in the null hypothesis. O Yes, this is a statement that compares a parameter to a value. O No, there is no parameter. O Yes, this is a statement that compares 2 values.
- Using P-value approach, the statement below will be used when the null hypothesis and alternative hypothesis are: 2xP(t 2 |t*|) Ho: μ = μο Hai με μο Ο Hai H = μο Ho: μ Μο Hg: μ = μο Ho: μ > μο Ο Ηο: μ = μο Ha: μ # μο Ha: μ = μο Ho: μ # μοThe figure below will be used when the null hypothesis and alternative hypothesis are: Ho: μ = μο Hai με μο Ha: H = μο Ho: H μο Ο Hai μ = μο Ho: μ > μο Ο Ηο: μ = μο Ha: μ # μο Ο Ha: Η = μο Ho: μ # μο 1-aIs the statement Ho: 14 = 6 a valid null hypothesis? Yes, this is a statement that compares a parameter to a value. Yes, this is a statement that compares 2 values. No, there is no parameter. No, equalities are not permitted in the null hypothesis.
- If the conclusion in a hypothesis test is to fail to reject H0H0, we can conclude that there is strong evidence that the null hypothesis is true.Based on the given, decide whether the null hypothesis is rejected or not.Is the statement H, := 4 a valid null hypothesis? No, equalities are not permitted in a null hypothesis. No, there is no parameter contained in this statement. O Yes, this is a statement that compares a parameter to a value. Yes, this is a statement that compares two parameters.
