Formulating the HypothesesIt is believed that the average commute time for an employee to and from their office in Hyderabad is at least 35 minutes. Now, suppose you want to test this claim.What will be the null and alternative hypotheses in this case if the average commute time is represented by μ?Ho: μ ≤ 35 minutes; Ha: μ > 35 minutesHo: μ > 35 minutes; Ha: μ ≤ 35 minutesHo: μ ≥ 35 minutes; Ha: μ < 35 minutesHo: μ < 35 minutes; Ha: μ ≥ 35 minutes

The average commute time for an upGrad employee to and from the office is at least 35 minutes.What will be the null and alternate hypotheses in this case if the average time is represented by μ? H₀: μ ≤ 35 minutes and H₁: μ > 35 minutesH₀: μ > 35 minutes and H₁: μ ≤ 35 minutesH₀: μ ≥ 35 minutes and H₁: μ < 35 minutesH₀: μ < 35 minutes and H₁: μ ≥ 35 minutes

Formulating the HypothesesGoodyear has launched a new tyre, which, it claims, can travel more than 7,500 miles before it needs any replacement.Assuming that the ‘average distance travelled before replacement’ is given by μ, what would be the null and alternative hypotheses in this case?Ho: μ ≤ 7500 miles; Ha: μ ≠ 7500 milesHo: μ ≤ 7500 miles; Ha: μ > 7500 milesHo: μ = 7500 miles; Ha: μ ≠ 7500 milesHo: μ ≥ 7500 miles; Ha: μ < 7500 miles

The pizza chain aims to deliver within 20 minutes on average. What would be the null and alternative hypotheses if the pizza chain wishes to conduct a hypothesis test to assess whether they have exceeded the target delivery time?a.H0 µ = 20 minutes, H1: µ ≠ 20minutesb.H0: µ = 20 minutes, H1: µ < 20 minutesc.H0: µ = 20 minutes, H1: µ > 20 minutesd.H0: µ < 20 minutes, H1: µ > 20 minutes

Suppose the commute times for employees of a large company follow a normal distribution. If the mean time is 22 minutes and the standard deviation is 5 minutes, 95% of the employees will have a travel time within which range?A.17.25 minutes to 26.75 minutesB.17 minutes to 27 minutesC.12 minutes to 32 minutesD.7 minutes to 37 minutesSUBMITarrow_backPREVIOUS

When Parker commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 58 minutes and a standard deviation of 4.5 minutes. Using the empirical rule, determine the interval that represents the middle 95% of his commute times.
