In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6964 subjects randomly selected from an online group involved with ears. There were 1298 surveys returned. Use a 0.01 significance level to test the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution. Identify the null hypothesis and alternative hypothesis. O A. Ho: p = 0.2 H:p<0.2...

7. Conduct a hypothesis test showing all of your steps. Females under the age of 51 years old are supposed to get, on average, 18 mg of iron daily. In a random sample of 44 women, their daily mean intake was 16.77 mg of iron with a standard deviation of 3.02 mg. An agency claims that women get less than the recommended daily iron intake. Test this claim with a 4% level of significance. a)...

At a certain college, it is estimated that at most 24% of the students ride bicycles to class. Does this seem to be a valid estimate if, in a random sample of 81 college students, 24 are found to ride bicycles to class? Use a 0.01 level of significance.
