- A bands name is generally recognized by 10% of college students. The band promotes itself heavily on one colleges radio station, and plans to continue to do this in all cities they plan to tour if the band is at least 90% certain that the percent of students who recognize the band has more than tripled. At a college where the band was promoted, 327 people are questioned, and 115 have heard of the band. Write HA, HO, and the Alpha level. What would the type-1 error be in this context? Run a test on the binomial calculator what is the p value.In the class poll from the beginning of the year, you were asked what color car you drive.

- It is often useful for retailers to determine why their potential customers chose to visit their store. Possible reasons include advertising, advice from a friend, or previous experience. To determine the effect of full-page advertisements in the local newspaper, the owner of an electronic-equipment store asked randomly selected people who visited the store whether they had seen the ad. He also determined whether the customers had bought anything, and if so, how much they spent. Among the respondents who saw the ad, 49 made an average purchase of $97.38 with a variance of $622. Among the respondents who did not see the ad, 21 made an average purchase of $92.01 with a variance of $283.3. Can the owner conclude that customers who see the ad spend more than those who do not see the ad (among those who make a purchase) at 5% significance level?

- The average total dollar purchase at a convenience store is less than that at a supermarket. Despite smaller-ticket purchases, convenience stores can still be profitable because of the size of operation, volume of business, and the markup. A researcher is interested in estimating the average purchase amount for convenience stores in suburban Long Island. To do so, she randomly sampled 24 purchases from several convenience stores in suburban Long Island and tabulated the amounts to the nearest dollar (shown below). $9 $7 $1 $2 $14 $11 $7 $8 $6 $7 $3 $3 $2 $5 $4 $4 $1 $2 $3 $10 $8 $8 $6 $4 Assume that the population standard deviation is 3.23 and the population is normally distributed. Using the above data, a 90% confidence interval for the population average amount of purchases is 4.54 to 6.71 4.495 to 6.76 4.44 to 6.81 4.49 to 6.76 4.26 to 6.99During the first 13 weeks of the television season, the Saturday evening 8 p.m. to 9 p.m. audience proportions were recorded as ABC 31%, CBS 26%, NBC 27%, and independents 16%.
