3. Elizabeth Loftus conducted research on eyewitness testimony. Participants watcheda short video of a car crash and were then asked how fast the car was going when ithit another vehicle. The question used different words when referring to "hit". 7participants heard the word “bumped", 7 participants the word "crashed" andanother 7 participants the word "smashed". The "bumped" group report an averagespeed of 25.145mph, the "crashed" group an average speed of 29.859mph and the"smashed" group a speed of 38.574mph.a. What test was done?b.

Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of ? = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 35 waves showed an average wave height of x = 17.3 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. H0: ? = 16.4 ft; H1: ? ≠ 16.4 ft H0: ? > 16.4 ft; H1: ? = 16.4 ft H0: ? < 16.4 ft; H1: ? = 16.4 ft H0: ? = 16.4 ft; H1: ? > 16.4 ft H0: ? = 16.4 ft; H1: ? <…

Imagine that the following four sentences are questions on a survey. Which question would produce data that belong to a discrete variable? A. How many years have you participated in track-and-field? B. What is the fastest time you’ve gotten on the 100 meter dash? C- How far can you throw a discus? D- What is your best track-and-field event?
Name Enrichment 1-7 A botanist is studying the development of a bamboo plant. She started keeping a log of its growth 25 weeks ago. Since then, the plant has grown an average of inch each week. Every 5 weeks, she trims 2, inches off the top of the bamboo plant. Its current height is 5 feet. 1. Write an equation to represent the plant's growth since the botanist started keeping her log. How much has the plant grown? 2. What is the change in the plant's height from being trimmed?
You want to figure out if there is a difference in lengths between male and female kestrels (kestrels are small falcons found all over Northern Virginia). You catch 10 females and 9 males with the following results (in cm) Females: 27.0 27.3 29.1 27.9 28.5 28.4 27.7 27.2 26.1 26.4 Males: 20.3 24.1 24.6 23.2 22.4 23.2 19.1 19.9 21.7 Is there a difference in lengths? Use α = .01. Note that you have to calculate everything yourself. Make sure you give H0 and H1 (symbols are okay), and clearly write out your conclusion.
