What could cause condition on tooth #20?  

A study was conducted to compare female and male college students based on the number of hours they spend watching television on weekends. Results are summarized below. Female group mean = 4.52Male group mean = 4.89Standard error for the difference the two sample means = 0.11 With the difference in population means defined as “Female minus Male” which of the following presents the correct test statistic?

What condition does this patient likely have? It is fungal in nature and commonly found in corners of mouth. Typically occurs during ortho treatment. 

What is the type of inflammation that is long lasting and causes extensive tissue destruction?

Explain the process of acute inflammation becoming chronic inflammation. What does this process look like clinically? Be as specific as possible.     

A researcher wants to compare the hand-eye coordination of men and women and determine if there is a difference in the mean time needed to complete a task. She finds a sample of 50 men and sample of 50 women for this study. Each person is asked to thread a needle where the time needed to complete this task is recorded in seconds. What is the correct alternative hypothesis for this hypothesis test?  

In a survey, students are asked how many hours they study in a typical week. A five-number summary of the responses is included.    Min Q1 Med Q3 Max 5 9 14 20 50   Use the information from this five-number summary to identify the quantities listed below.

Research Question: A certain species of prairie flower is reported to receive on average 12 different species of pollinators per hour. A researcher thinks the average is actually higher.  A randomization distribution (based on 100 samples) has been created assuming the null hypothesis is true. To test this claim, the researcher finds 30 different plants of this species to observe and sets up cameras for each plant. After reviewing all of the footage captured over 1 hour, the reported sample average number of species to visit the prairie flowers is 13.8 The sample mean [answer1] provide convincing evidence that the average number of pollinators to visit is greater than 12 because the p-value of [answer3] is [answer2] than 0.05.

Suppose that for a random sample of 400 students a 90% confidence interval for the proportion of first-year students at a school who played in intramural sports is 35% plus or minus 5%. The level of confidence is [answer1].  The margin of error is [answer2].

A functional dexterity test was given to children of different ages where the time needed to complete the test was recorded in seconds when using the non-dominant hand.  The test involved turning over 16 pegs as fast as possible when following a certain sequence.  The data was used to obtain the Minitab output found below. Classify each statement below as true or false.
