Students in SC 130 Physical Science were measuring bars of Dial Soap and obtained the following data:
1 On a penny with a head and a tail, what is the probability of heads prior to tossing the coin? 2 On a six sided die numbered from one to six, what is the probability of rolling a three? 3 While out on a five kilometer run on Wednesday evening I kept track of the make of the cars using a scrap pad of paper and a pen. I recorded each manufacturer for each car I saw on the road during my 41 minute run. During the run I made hash marks |||| next to manufacturer names. When I returned home I tallied up the counts from the run and made the following table: Manufacturer Frequency Relative Freq Toyota 90 30% Nissan 51 17% Mazda 42 14% Honda 36 12% Mitsubishi 32 11% Suzuki 14 5% Hyundai 12 4% Ford 7 2% Kia 6 2% Isuzu 5 2% BMW 2 1% Daihatsu 1 0% AMC Jeep 1 0% Mercedes Benz 1 0% 300 1 For this data, what is the level of measurement? Multiple Choice - 0 points 4 For the automobile manufacturer data above, the sample size n is _ Fill in the Blank - 2 points 5 For the automobile manufacturer data above, the mode is _ Fill in the Blank - 2 points 6 Based on the automobile sample above, what is the probability that a car on the roads of Pohnpei is a Toyota? _ (Your answer can be a percent with a percent sign or a two decimal place decimal value using a decimal point) Fill in the Blank - 2 points 7 Kia and Hyundai cars are made in South Korea. Based on the automobile sample above, what is the probability that a car on the roads of Pohnpei is made in South Korea? _ (Your answer can be a percent with a percent sign or a two decimal place decimal value using a decimal point) Fill in the Blank - 2 points 8 Plastic beads were thrown into the air and fell on the floor in the pattern seen in the following image. The horizontal distribution is in centimeters marked along the x-axis. What is the best estimate for the horizontal mean for this plastic bead distribution? 9 Plastic beads were thrown into the air and fell on the floor in the pattern seen in the following image. The horizontal distribution is in centimeters marked along the x-axis. What is the best estimate for the horizontal standard deviation for this plastic bead distribution? 10 Based on a histogram, does the horizontal bead distribution appear to be roughly a normal distribution?
