What is a scatter plot? * O A graph that shows information that is connected in some way. A graph drawn using rectangular 0 bars to show how large each value is. O A graph that shows data changing overtime. O A graph that shows the relationship of two data sets. The given Scatter diagram indicates * that Choose it has a strong positive correlation it has a moderate positive correlation it has a weak positive correlation it has no correlation What is the significance of the rejection region? If the test statistic lies inside the O rejection region, we will fail to reject the null hypothesis If the test statistic lies outside the O rejection region, we will fail to reject the null hypothesis If the test statistic lies outside the O rejection region, we will reject the null hypothesis O The rejection region has no significance. is According to a survey, 68% of the mothers are willing to spend extra money on their children's education and health matters. Lately, a random sample of 1000 mothers revealed that 73% of the mothers are willing to give extra money on their children's education and health matters. Is the percentage of all such mothers increased? Identify the rejection region for this example. 0 The rejection regions are located at both tail of the distribution curve The rejection region is located at the left tail of the distribution curve The rejection region is located at the right tail of the distribution curve It cannot be determined because of lack of data. 000 3': The figure below shows a normal curve with its rejection region shaded. The red dot shows the calculated test statistic. Is the test onetailed or twotailed? O The test is one-tailed, left tail 0 The test is one-tailed, right tail 0 The test is two-tailed O The test has no tail
