Lilo wants to know if equal proportions of students in her class know how to surf well, know how to surf a little or do not know how to surf. She randomly samples 60 students in her class and asks them if they know how to surf. Twenty students indicate that they do not know how to surf 'don't know', while 30 students indicate they know how to surf well 'know well,' and 10 students indicate they know how to surf ‘a little’. State the hypothesis being tested by Lilo (H0 and HA)? Test Lilo's hypothesis at α of .05. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = Critical value = Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"):

You will simulate shooting basketball free throws. Using any coin, let heads represent the ball going into the basket and tales represent the ball missing the basket. Each toss of the coin represents a shot at the free throw line. Simulate shooting 35 free throws. Make a chart on your paper similar to the one below to record your results. For each trial (toss), place an x in the appropriate column. Toss number 1 2 Went in (Heads) X Questions: 1. How many free throws went into the basket? 2. How many free throws missed the basket? Missed (Tails) X 3. What is the experimental probability that you will make the next free throw? 4. What is the experimental probability that you will miss the next free throw? 5. This simulation assumes that you have an equal chance of making the free throw or missing the free throw. Is this a correct assumption? Why? 6. How would you change this simulation to better predict a person's abilities at making free throws?
A large group of people get together. Each one rolls a die 120 times, and counts the number of aces (with a single dot). About what percentage of these people should get counts in the range 10 to 30? Choose the closest answer.
Recently a community college offered a 2-credit course to help students with math anxiety. At the beginning of the course, each student took a 30-question survey (called MARS-S); the higher the score, the more anxiety experienced by the student. The nine students remaining in the class took the same survey at the end of the course. The before and after scores for each of the nine students who completed the course are shown below, student before after 1 72 69 66 52 3 83 71 97 85 95 61 78 45 95 56 8. 52 43 93 62 Compute the correlation between before and after scores for these students.

As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.

Experimental or Observational: A group of students is interested in knowing if the number of times they can sink a basketball is related to the color of the basketball. The students shoot a series of baskets and record their success using a regulation colored basketball. They then switch to a blue colored basketball and shoot the same series of baskets. .
