In a random sample of 40 dog owners enrolled in obedience training, it was determined that the mean amount of money spent per owner was $107.89 per class with a standard deviation of $8.20. Construct and interpret a 95% confidence interval for the mean amount spent per owner for an obedience class.

Ten years ago, a random sample of 257 dog owners was taken and it was found that 146 owned more than one dog. Recently, a random sample of 380 dog owners showed that 200 owned more than one dog. Do these data indicate that the proportion of dog owners owning more than one dog has decreased? Use a 5% level of significance. State the null and alternate hypotheses. Is the test left-tailed, right-tailed, or two- tailed? Identify the appropriate sampling...

A group of n = 25 students was selected at random for studies related to the amount of time they spent for exam preparations. Educators assume that individual records are normally distributed with entirely unknown parameters (μ, σ). Sample summaries (in minutes per week) were obtained as Sample Mean =X =90 and Sample SD =s=20 For hypothesis testing, set significance level = α = 0.01̄ To test whether μ < 100, what critical value (or values) are you going to...

Students in Physics and Chemistry a random sample was taken from 20 students in Physics, from which an average of 3 hours per week was obtained with a deviation. typical of 2.5 hours, and another sample of 30 independent chemistry students from the previous one, which presented an average of 2.8 hours, with a deviation. typical 2.7h. Assuming that the weekly study hours of the two types of students follow a normal distribution, (a) Calculate a 95% confidence interval for...
