The floor exercise is a commonly shared event between the Women’s and Men’s Artistic Gymnastics programs. Let’s compare the floor exercise scores of the female gymnasts and male gymnasts. To do this, we will consider the 2007, 2011, and 2015 results as sample data. Part B: Apparatus Finals Let’s now look at the floor exercise scores in the Female Apparatus Finals and in the Male Apparatus Finals.

Suppose you know the population average wage in the manufacturing industry in the U.S. is $26.72 per hour. You take a survey 40 people that work in manufacturing in Spain to answer the following research question. Research Question: Is the population average manufacturing wage in Spain less than $26.72 per hour, the population average manufacturing wage in the U.S.? Y ou find a sample mean of $25.50 from your survey of workers in Spain. You know the population standard deviation for manufacturing wages in Spain is $2.60 per hour. Suppose you are using a significance level of 0.01 or 1% (α = 0.01). True or False: You will reject the null hypothesis and conclude that the true average manufacturing wage in Spain is less than the true average manufacturing wage in the U.S.

The problem is It is widely believed that 19% of all students live in campus housing. You suspect that claim is not accurate. You take a sample of 150 students from the population and find that 39 of those students live in campus housing. The part I am having trouble with is: Assuming the null is true, how many standard errors is the sample proportion away from the null? I need help remembering how to find the standard error. I know that the answer is 2.19.
