USA Today reported that about 47% of the general consumer population in the United States is loyal to the automobile manufacturer of their choice. Suppose Chevrolet did a study of a random sample of 1001 Chevrolet owners and found that 482 said they would buy another Chevrolet. Does this indicate that the population proportion of consumers loyal to Chevrolet is more than 47%? Use α = 0.01.
(a) What is the level of significance?
State the null and alternate hypotheses.
H0: p > 0.47; H1: p = 0.47
H0: p = 0.47; H1: p ≠ 0.47
H0: p = 0.47; H1: p < 0.47
H0: p = 0.47; H1: p > 0.47
(b) What sampling distribution will you use?
The standard normal, since np < 5 and nq < 5.
The Student's t, since np > 5 and nq > 5.
The standard normal, since np > 5 and nq > 5.
The Student's t, since np < 5 and nq < 5.
What is the value of the sample test statistic? (Round your answ

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
