An insurance company crashed four cars of the exact same model at 5 miles per hour. The costs of repair for each of the four crashes were $433, $440, $495, and also $207 . Compute the expect, median, and mode price of repair.

The adhering to data represent the weights (in grams) of an easy random sample of a candy.0.900.870.830.920.900.860.860.870.810.84 Determine the form of the circulation of weights of the candies by illustration a frequency histogram and also computer the mean and the median. Which measure of central tendency ideal defines the weight of the candy?
A professor has actually taped exam grades for 10 students in his course, however among the grades is no longer readable. If the mean score on the exam was 82 and also the mean of the 9 readable scores is 86, what is the worth of the unreadable score?
The typical deviation is provided in conjunction with the ______ to numerically define distributions that are bell shaped. The ______ procedures the center of the distribution, while the typical deviation steps the ______ of the distribution.
True or False: When comparing two populaces, the bigger the standard deviation, the more dispersion the distribution has actually, provided that the variable of interemainder from the 2 populations has actually the exact same unit of meacertain.
True, bereason the traditional deviation explains how far, on average, each observation is from the typical worth. A larger conventional deviation indicates that monitorings are more far-off from the typical value, and therefore, more spread.
True or False: Chebyshev"s inetop quality uses to all distributions regardless of shape, but the empirical rule holds just for distributions that are bell shaped
True, Chebyshev"s inequality is less precise than the empirical dominion, yet will certainly job-related for any distribution, while the empirical dominion just functions for bell-shaped distributions
the empirical ascendancy can be used to identify the portion of information that lie within k traditional deviations of the suppose. To help organize the empirical dominance and also make the analysis simpler, draw a bell-shaped curve, as presented to the appropriate. The line in the facility of the curve represents the expect. The various other lines are each 1, 2, and also 3 standard deviations ameans from the intend.

Any normal circulation is a symmetric circulation which constantly has actually a intend worth of zero and also a standard deviation of one.
