10. Construct a sample (with at least two different values in the set) of 4 measurements whose mean, median, and mode are equal. If this is not possible, indicate "Cannot create sample".
Selecting a checkbox will replace the entered answer value(s) with the checkbox value. If the checkbox is not selected, the entered answer is used.
Cannot Create Sample
There are infinite samples possible which will satisfy the given requirement. One such sample will be:
5, 6, 6, 7
For the above data set:
Mean = Median = Mode = 6
10. Construct a sample (with at least two different values in the set) of 4 measurements...
Construct a sample (with at least two different values in the set) of 3 measurements whose mode is smaller than all the members in the sample. If this is not possible, indicate "Cannot create sample".
Construct a sample (with at least two different values in the set) of 5 measurements whose mode is smaller than at least 1 of the 5 measurements.
8. Computing the median for discrete and continuous variables Aa Aa Consider the sample of n 5 scores whose frequency distribution histogram is shown here. Divides Area in Half Clear All The total area in the histogram boxes. Half the area in the histogram boxes. Add a vertical line to the frequency distribution histogram that divides the total area exactly in half. In other words, place the vertical line so that it makes the area on the right and left...
The range of a set of measurements is the difference between the largest and the smallest values. The empirical rule suggests that the standard deviation of a set of measurements may be roughly approximated by one-fourth of the range that is, -**, G range The acidity of soils is measured by a quantity called the pH, which may range from 0 (high acidity) to 14 (high alkalinity). A soil scientist wants to estimate the average pH for a large field...
The following measurements (in picocuries per liter) were recorded by a set of argon gas detectors installed in a research facility: 831.7, 847.2, 820.9, 826.3 Using these measurements, construct a 95% confidence interval for the mean level of argon gas present in the facility. Assume the population is approximately normal. Step 1. Calculate the sample mean for the given sample data. Round your answer to two decimal places. Answer: ____________________ Step 2. Calculate the sample standard deviation for the given...
The following measurements (in picocuries per liter) were recorded by a set of radon gas detectors installed in a laboratory facility: 382, 361.2, 333, 348.3, 385.1, 332.2, 380.7 Using these measurements, construct a 95 % confidence interval for the mean level of radon gas present in the facility. Assume the population is approximately normal. Copy Data Step 3 of 4: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places...
The following measurements (in picocuries per liter) were recorded by a set of xenon gas detectors installed in a waste disposal facility: 622.2, 619.6, 632.4, 652.8, 634.4, 637.3 Using these measurements, construct a 95% confidence interval for the mean level of xenon gas present in the facility. Assume the population is approximately normal. Step 1 of 4: Calculate the sample mean for the given sample data. Round your answer to two decimal places. Step 2 of 4: Calculate the sample...
Calculating Mean, Median, and Mode (Individual Data) Individual data – represents individual values in a set. Mean – is the average value of the values in a set. It is calculated by dividing the sum of the individual values in a set by the number of values in that set. Median – better represents a measure of central than the mean in a set of data that are skewed one direction or another. To calculate the median value of individual...

way.
Three randomly selected households are surveyed. The numbers of people in the households are 1, 4, and 10' Assume that samples of size n 2 are randomly selected with replacement from the population of 1, 4, and 10. Construct a probability distribution table that describes the sampling distribution of the proportion of even numbers when samples o sizes n = 2 are randomly selected Does he mean o the...
