PDF page 516: Television Survey In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.

PDF page 517: Language Survey About 42.3 percent of Californians and 19.6 percent of all Americans over age five speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percentage of the students at your school who speak a language other than English at home is different from 42.3 percent.

PDF page 519: hypothesis a statement about the value of a population parameter; in the case of two hypotheses, the statement assumed to be true is called the null hypothesis (notation H0) and the contradictory statement is called the alternative hypothesis (notation Ha) hypothesis testing based on sample evidence, a procedure for determining whether the hypothesis stated is a reasonable statement and should not be rejected, or is unreasonable and should be rejected level of significance of the test probability of a Type I error (reject the null hypothesis when it is true) Notation: α. In hypothesis testing, the level of significance is called the preconceived α or the preset α. normal distribution a bell-shaped continuous random variable X, with center at the mean value (μ) and distance from the center to the inflection points of the bell curve given by the standard deviation (σ) We write . If the mean value is 0 and the standard deviation is 1, the random variable is called the standard normal distribution, and it is denoted with the letter Z.
