Find to/2 for a 95% confidence interval of μDMD - μHealthy. Round your
answer to three decimal places.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.

Indicate the statistical test you would conduct. Respondents in a survey of 1,000 households were asked about their travel history. Specifically, they were asked how often they have been to Europe in the past five years (using a ratio scale). People were also classified by interest type (art-lovers, food-lovers, or sports-lovers). The question is whether interest type influences travel history. Two-sample t-test Paired sample t-test One-way ANOVA none of those QUESTION 6 What is the corresponing alternative hypothesis for the scenario in question #5? The three interest types do not differ with regard to the number of times they have been to Europe in the last five years. Interest type and travel to Europe are not related. The number of times people have been to Europe does not depend on interest type. The three interest types differ with regard to the number of times they have been to Europe in the last five years.
