an anthropologist claims that 12% of humans are left-handed. Based on a random sample of 110 humans you find 18% are left-handed. Does the sample suggest the percentage of left-handed humans is greater than that claimed by the anthropologist?

Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 130 people from the U.S. is chosen, approximate the probability that at most 14 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.

We will be using Excel to simulate the number of left-handed people in a particular sample. Left-handed people make up about 10% of the population. We will randomly pick numbers between 1 and 10, where 1 represents a left-handed person and 2 - 10 represents a right-handed person. This should result in about 10% of our sample being left-handed. Please note there are five parts to this question. 1. Create a pie graph in Excel to show the proportion of...

9) A candy company claims that 12% of its plain candies are orange, and a sample of 100 such candies is randomly selected. a. Find the mean and standard deviation for the number of orange candies in such groups of 100. μ =___________ (Do not round). σ=______________ (Round to one decimal place as needed). A random sample of 100 candies contains 16 orange candies. Is this result unusual? Does it seem that the claimed rate of 12% is wrong? A....

a Soccer ball manufacturer claims the diameters of their ball have a standard deviation of 2 mm when properly inflated. Based on a random sample of 10 balls you find a standard deviation of 3.2 mm. DOES the sample suggest the standard deviation is higher than that claimed by the manufacturer?

A soccer ball manufacturer claims the diameters of their ball have a standard deviation of 2 mm when properly inflated. Based on a random sample of 10 balls you find a standard deviation of 3.2 mm. Does the sample suggest the standard deviation is higher than that claimed by the manufacturer? What are the necessary steps to solve this problem?
