- The conditional probability of E given that F occurs is P(EF)=___________. So in rolling a die the conditional probability of the event E, getting a six, given that the event F, getting an even number, has occurred is P(EF)=___________.The null and alternative hypotheses are given.

Right-tailed, σ D.) Right-tailed, μThe null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed and the parameter that is being tested.H0: μ = 9.0H1: μ ≠ 9.0
- the null and alternative hypothesis are given. h0: p= 0.84 h1: pgreater than .84 determine left, right or two tailed and the parameter that is being testedA supplier claims that the true mean electrical resistance of wiring harnesses of a certain model is 30 ohms. A manufacturer that uses this harness wants to test whether this claim is true. Which of the following is the correct pair of hypotheses to use for this hypothesis test? Pick the right answer below by quoting the numbered point. 1. H0:μ=30 and H1:μ≠30 2. H0:μ⩾30 and H1:μ<30 3. H0:μ⩽30 and H1:μ>30 4. H0:μ≠30 and H1:μ=30 5. H0:μ<30 and H1:μ⩾30 6. H0:μ>30 and H1:μ⩽30The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, righttailed, or two-tailed and the parameter that is being tested.

A one-sample t test will be carried out to see whether this is the case. What conclusion is appropriate in each of the following situations? (a) n = 12, t = 1.56, ? = 0.05 Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in.Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. Do not reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in.Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. (b) n = 12, t = −1.56, ? = 0.05 Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in.Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. Do not reject the null hypothesis. There is sufficient evidence…Conduct the hypothesis test for H0: µ = 10 versus Ha: µ =/10 (i.e µ is not equal to 10) where x bar = 9.6 and s = 3, n = 50.
