Perform the appropriate Hypothesis Test (State the Null Hypothesis, Alternative Hypothesis, the appropriate test statistic, the p-value, whether you reject or fail to reject the null, and then interpret your conclusion): A simple random sample of 200 drivers were asked if they drive a car manufactured in a certain country. Of the 200 drivers surveyed, 107 responded that they did. Determine if more than half of all drivers drive a car made in this country. Use α=0.025.

For the standardized test statistic approach to hypothesis testing, calculate the test statistic for testing the null hypothesis that the population mean is less than or equal to 10.70, given a sample mean of 12.30, a sample size of 30, and a population standard deviation of 2.61.

For the standardized test statistic approach to hypothesis testing, calculate the test statistic for testing the null hypothesis that the population mean is less than or equal to 9.94, given a sample mean of 15.20, a sample size of 49, and a population standard deviation of 3.25. Round to two decimals.

Use the given information to calculate and interpret the test statistic and effect size. Hypotheses: H0: μ=20 vs. HA: μ≠20 Sample data ¯x=19.8 SD=1.5 SE=0.25 The test statistic is? =This means that the point estimate is_____ standard errors below the null value. The effect size is ______ , which can be considered (select answer: Small, moderate, large) Differences between the point estimate and the null value will not be noticeable without careful observation.

State the test statistic and P-value. Interpret these values. For the 30 women in the study with a history of premature labor, a proportion of 18/30 = 0.60 (60%) had babies with low birth weight. For the remaining 159 women, a proportion of 41/159 = 0.26 (26%) had babies with low birth weight. We now investigate the following research question: do the data provide evidence that the proportion of babies born with low birth weight is higher for women with...
