I'm kind of confused about which 'sign' I should use and whether it's one-tailed or two-tailed. The body mass index (BMI) of a person is the person's weight divided by the square of his or her height. It is an indirect measure of the person's bodyfat and an indicator of obesity. Results from surveys conducted by the Centers for Disease Control and Prevention (CDC) showed that the estimatedmean BMI for US adults increased from 25.0 in the 1960-1962 period to 28.1 in the 1999-2002 period. [Source: Ogden, C., et al. (2004). Mean bodyweight, height, and body mass index, United States 1960-2002. Advance Data from Vital and Health Statistics, No. 347.]Suppose you are a health researcher. You conduct a hypothesis test to determine whether the mean BMI of US adults in the current year is greaterthan the mean BMI of US adults in 2000. Assume that the mean BMI of US adults in 2000 was 28.1 (the population mean). You obtain a sample ofBMI measurements of 1,034 US adults, which yields a sample mean of M = 28.9.Let u denote the mean BMI of US adults in the current year. Formulate your null and alternative hypotheses by selecting the appropriate values in theblue dropdown menus that follow.Ho:H₁:The test you conduct istest.

A reporter for a local television station visits the city's new upscale shopping mall the day before Christmas to interview shoppers. He questions the first 25 shoppers he meets outside one of department stores at the mall. He asks them whether their overall feelings about Christmas shopping are positive, neutral, or negative. Select the reason(s) why it may be risky to act as if the first 25 shoppers at this particular location are an SRS of all shoppers in the city. Surveying shoppers the day before Christmas is a convenience sample, so it is a simple random sample. Shoppers at the mall the day before Christmas does not guarantee every shopper in the population has an equal chance to be in the sample. Surveying shoppers at the mall the day after Christmas may not be a good represenation of all shoppers in the city. Having the reporter ask questions is not a double‑blind study.
