  1. A sample of 152 statistics students were surveyed concerning their future pet ownership. Of the 152 students in the sample, 82 responded that they plan on getting a dog after graduating.
    1. Construct a 95% confidence interval for the proportion of statistics students overall (i.e., the entirepopulation) that want to get a dog.
    2. Suppose we wanted to take another sample to estimate the percent of percentage of statistics students that want to get a dog. Find the sample size we need to estimate the percent of percentage of statistics students that want to get a dog. Use the estimate from the sample for the sample proportion, a margin of error of 4% and a confidence level of 99%.

At the beginning of the Summer 2018 semester, a sample of 266 World Campus students were surveyed and asked if they were a first-generation college student. In the sample of 266, 139 said that they were first generation college students. We want to construct a 90% confidence interval to estimate the proportion of all World Campus students who are first generation students. A. In StatKey, construct a bootstrap distribution and use the percentile method to find the 90% confidence interval...

Researchers were interested in the relationship between mental health and living with a pet. Students were surveyed and grouped by pet type as either “Cats”, “Dogs”, or “No Pets”, and completed a scale on depressive symptoms on a scale of 1-7, where 7 indicates high levels of depressive symptoms. Using the data in the frequency table below, please conduct a one-way ANOVA to determine if there are any significant differences between these groups. Use α = .05, report η², and...

2. Data concerning employment status were collected from a sample of 50 World Campus students. In that sample of 50 students, 33 students reported they were employed full-time. A. Use Minitab Express to construct a 95% confidence interval to estimate the proportion of all World Campus students who are employed full-time. If assumptions were met, use the normal approximation method. Remember to include all relevant Minitab Express output and to clearly identify your answer. [15 points] B. What sample size...
