Question

The mean of the paired differences d. Critical value. Standard deviation. Lower and upper endpoint. Thank you

On this page, we examine an experiment conducted by two commuters, A and B, who typically travel to work together. They aim to determine if one route is consistently faster than the other. Both men believe their driving habits are quite similar, so they rotate routes over two weeks, each taking turns on Route I and Route II. The travel durations, precise to the nearest minute, are recorded in the table below:

Let \( d = (\text{Route I travel time}) - (\text{Route II travel time}) \).

Assumption: The travel times for both routes are normally distributed.

### Recorded Travel Times (in minutes)

| Day | M | Tu | W | Th | F | M | Tu | W | Th | F |
|------|-----|----|----|----|-----|----|----|----|----|----|
| Route I | 34 | 24 | 31 | 28 | 27 | 31 | 31 | 28 | 28 | 24 |
| Route II | 35 | 26 | 28 | 29 | 24 | 33 | 34 | 29 | 32 | 25 |

### Step 4 of 4: Construct the 98% Confidence Interval

Instructions: Use the given data to construct a 98% confidence interval for the true mean difference between the travel times of Route I and Route II. Ensure to round your final answers to one decimal place.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
