A thermometer reading 70F is taken outside. Five minutes later the thermometer reads 40F. Thirty-five minutes after being taken outside, the thermometer reading is within one-half a degree of the outside temperature. Find the value of the outside temperature assuming it is constant. Ans. 9.5oF What is the solution?

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
