Provide an appropriate response. A is a statement or claim regarding a characteristic of one or more populations. A) conjecture B) fact C) conclusion D) hypothesis The _____ hypothesis contains the " =" sign. A) explanatory B) conditional C) alternative D) null A hypothesis test is a "two-tailed" if the alternative hypothesis contains a _____ sign. A) C) notequalto D) = Given H_0: mu lessthanorequalto 25 and H_a: mu > 25, determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. A) two-tailed B) right-tailed C) left-tailed A car maker claims that its new sub-compact car gets better than 47 miles per gallon on the highway. Determine whether the hypothesis test for this is left-tailed, right-tailed, or two-tailed. A) left-tailed B) right-tailed C) two-tailed A researcher claims that 73% of voters favor gun control. Determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. A) two-tailed B) right-tailed C) left-tailed Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (mu, p, sigma) for the indicated parameter. An entomologist writes an article in a scientific journal which claims that fewer than 7 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light. A) H_0: p > 0.0007 H_1: p lessthanorequalto 0.0007 B) H_0: p lessthanorequalto 0.0007 H_1: p > 0.0007 C) H_0: pExplanation / Answer
Solution:-
1) A hypotheis is a statement or claim. (D)
2) The null hypothesis cotains equals sign. (D)
3) A hypothesis test is a two-tailed, if the alternate hypothesis contains not equal sign. (C)
4) Right-tailed. (B)
5) As it says better that mean we will use null hypothesis as mu >= 47 and the alternate will be mu < 47.
So, its Left-tailed. (A)
6)Here, null hypothesis will be, mu = 0.73 and alternate will be not equal to 0.73. Thus, its two-tailed.(A)
7) (C)
8) (D)
9) (B)
10) (D)
