We can infer a statistically significant difference between two population means when

a) our estimates of the two means are different. d) the 95% confidence intervals for the two means do not overlap.

b) the variances of the two means do not overlap. e) the 95% confidence intervals for the two means are of different widths.

c) the standard deviations of the two means do not overlap.

Expert Solution

Option D is correct

whwn the 95% confidence interval for the two means do not overlap there will be a statistically significant difference between the means (at the 0.05 level of significance)

A) Can we assume the difference between means of population 1 and 3 is equal to 2 with 97% confidence level? (Answer it using hypothesis testing with confidence interval). Population 1: N(μ1,δ12) Sample from Population 1: 2, 4, 8, 3, 9, 10, 11, 15, 19 Population 3: N(μ3,δ32) Sample from Population 3: 11, 13, 7, 14, 10, 30, 13, 3, 20

Consider the following statements. (i). If we are testing for the difference between two population means, it is assumed that the sample observations from one population are independent of the sample observations from the other population. (ii). If we are testing for the difference between two population means, it is assumed that the two populations are approximately normal and have equal variances. (iii). The critical value of t for a two-tail test of the difference of two means, a level...

A researcher is interested in understanding if there is a statistically significant difference between people in different marital status in terms of their level of general happiness. Marital status was measured as follows: 1. Married, 2. Widowed, 3. Divorced, 4. Separated, and 5. Never married. General happiness was measured as follows: 1. Very happy, 2. Pretty happy, and 3. Not too happy. To test his hypothesis, the researcher ran the Analysis of Variance (ANOVA), and he obtained the following output table. ANOVA...

We want to assess whether there is a statistically significant association between two variables. Below are pairs of variables, along with their method of measurement. Indicate, justifying it in two lines, for each pair, which statistical test you would use. a) Total Cholesterol (mmol/l) and Sex (Male/Female). b) Red blood cells (millions/microlitre of blood) and Body Mass Index (kg/m2). c) Foot Pain (Severe/Levere) and Obesity (Yes/No). d) Marital status (Single/Married/Divorced) and Educational level (Primary/Secondary/University studies). e) Type 2 diabetes (Yes/No)...
