(CO 5) A used car dealer says that the mean price of a three-year-old sport utility vehicle in good condition is $18,000. A random sample of 20 such vehicles has a mean price of $18,450 and a standard deviation of $1930. At ?=0.08, can the dealer's claim be supported assuming the population is normally distributed?

O Yes, since the p-value of 0.310 is greater than alpha of 0.08, the null is not rejected. The claim is the null, so is supported O No, since the p-value of 0.310 is less than alpha of 0.08, the null is rejected. The claim is the null, so is not supported O No, since the p-value of 0.310 is close to the alpha of 0.08, the null is not rejected. The claim is the null, so is supported O Yes, since the p-value of 0.310 is less than alpha of 0.08, the null is rejected. The claim is the alternative, so is supported{CO 5} A researcher wants to determine if eating more vegetables helps high school juniors learn algebra. Ajunior class is divided into pairs and one student from each pair has extra vegetables and the other in the pair does not. After 2 weeks, the entire class takes an algebra test and the results of the two groups are compared. To be a valid matched pair test, what should the researcher consider in creating the two groups? 0 That the group with the extra vegetables also has more sweets 0 That each pair of students has similar his or abilities in mathematics 0 That each pair of students has similar ages at the time of the testing 0 That the group without extra vegetables receives different instruction
