The question isn't incomplete, this is what we are given, there isn't a significance level, just this question 1. A teacher for a large math class wants to know if her students scored higher on the first examthan usual this semester. From prior experience, the test scores have a mean score of 85 andstandard deviation 6.85. This semester, the average score for a random sample of 35 students inher class was 87 with standard deviation 7.5.Is there sufficient evidence to show that the class average this semester is higher than previousyears? Support your answer with the p-value approach. Make sure to include everything requiredfor a hypothesis test! (Assumptions, hypotheses, test statistic, decision and conclusion)

The random variable test score follows normal distribution. We have to test whether the class…

Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of bullies and a group of victims using an 18-item, 5-point anxiety scale. Assume scores on the anxiety scale are normally distributed and that the variances of the anxiety scores are the same among bullies and victims. The group of 23 bullies scored an average of 40.1 with a sample standard deviation of 10 on the anxiety scale. The group of 28 victims scored an average of 46.8 with a sample standard deviation of 11 on the same scale. You do not have any presupposed assumptions about whether bullies or victims will be more anxious, so you formulate…
