The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) during their freshman year. Listed in the accompanying table are weights (kg) of randomly selected male college freshmen. The weights were measured in September and later in April. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Complete parts (a) through (c). September 49 52 54 56 59 74 64 75 74 April 50 53 56 58 62 78 68 82 69 a. Use a 0.01 significance level to test the claim that for the population of freshman male college students, the weights in September are less than the weights in the following April. In this example, Had is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the April weight minus the September weight. Whe are the null and alternative hypotheses for the hypothesis test? Ho Hd 0 kg H₁ Hd >0…

The distribution of the sample proportion is approximately normal for large sample sizes. b. The mean of the sample proportion is equal to the population proportion of successes, p. c. The variance of the sample proportion always decreases as the population proportion of successes decreases. d. The variance of the sample proportion is equal to p(1-p) divided by the sample size, n. e. As the population proportion increases, the mean of the sample proportion increases. Previous page Nex

Histograms of random sample data are often used as an indication of the shape of the underlying population distribution. The histograms on the next page are based on random samples of size 30,50 and 100 from the same population. a. Using the midpoint labels of the three histograms, what would you say about the estimated range of population data from smallest to largest? Does the bulk of the data seem to be between 8 and 12 all in three histograms? b. The population distribution from which the samples were drawn is symmetric and mound shaped, with the top of the mound at 10,95% of the data between 8 and 12, and 99.7% of data between 7 and 13. How well does each histogram reflect these characteristics?
