(3) The weights of adult black squirrels are known to be normally distributed with mean µ and standard deviation o = 0.12 lbs. A random sample of nine black squirrels gave their average weight to be o.78 lbs. It is hypothesized that due to various reasons the black squirrels are becoming heavier. If the null hypothesis isHo : H s 0.75 lbs, versus H1 : µ > 0.75 find the p-valueThe following``answers" have been proposed.(a) By consulting a standard normal table, the p-value issup P(X9 2 0.78) = P(Z > 1.645) = 0.05.HS0.75(b) By consulting a standard normal table, the p-value issup P(X9 2 0.78) = P(Z > 1.00) = 0.1587.HS0.75(c) By consulting a standard normal table, the p-value issup P(X9 2 0.78) = P(Z > 0.75) = 0.2266.µ<0.75(d) By consulting a standard normal table, the p-value issup P(X9 2 0.78) = P(Z > 0.50) = 0.3085.µ<0.75(e) None of the aboveThe correct answer is(a)(b)(d)N/A(Select One)

A sample of 10 from population 1 has a mean of 32 and a standard deviation of 6. A sample of 13 from population 2 has a mean of 48 and a standard deviation of 8. The population standard deviations are unknown but assumed to be equal. Test the hypothesis, at the 1% level of significance, that the population means are the same. State your conclusion as a sentence and include the test statistic and the critical value.
A researcher is testing a hypothesis of a single mean. The critical t value for a = .05 and a one-tailed test is 2.0639. The observed t value from sample data is 1.742. The decision made by the researcher based on this information is to the null hypothesis. reject not reject redefine change the alternate hypothesis into restate

Records indicate that the mean weight of mature rainbow trout in Eagle Creek is 2.25 kg with a standard deviation of 0.53 kg. After years of marked oxygen depletion from pollutants in the creek, you want to perform a hypothesis test to see if the standard deviation, σ, of weights has changed. To do so, you measure the weights of 16 randomly chosen mature rainbow trout from the creek and find that the sample standard deviation is 0.34 kg. Under the assumption that current weights of mature rainbow trout in the creek follow a normal distribution, you will perform a chi-square test.Find χ2, the value of the test statistic for your chi-square test. Round your answer to three or more decimal places.=χ2

Using traditional methods it takes 107 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 150 students and observed that they had a mean of 106 hours. Assume the population standard deviation is known to be 5 . Is there evidence at the 0.01 level that the technique performs differently than the traditional method? Step 1 of 6 : State the null and alternative hypotheses.
