Underinflated or overinflated tires can increase tire wear and decrease gas mileage. A manufacturer of a new tire tested the tire for wear at different pressures. Construct scatterplot and calculate Pe, arson. Corr. Coeff. The reasearcher for this study calcualted a pearson correlation coefficient and concluded no relationships existed between the two variables. Was he correct in his conclusion?
col1 Pressure - 30, 30, 31, 31, 32, 32, 33, 33, 34, 34, 35, 35, 36, 36
col2 Milege (thous) - 29.5, 30.2, 32.1, 34.5, 36.3, 35, 38.2, 37.6, 37.7, 36.1, 33.6, 34.2, 26.8, 27.4

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
