A government report says that the average amount of money spent per US houschold per week on food is about $158. A random sample of 50 households in a small city is selected, and their weekly spending on food is recorded. The sample data
have a mean of $165 and a standard deviation of $32. Is there convincing evidence that the mean
weekly spending on food in this city differs from the
national figure of $158?
(a) State appropriate hypotheses for performing a
significance test in this setting Be sure to define the
parameter of interest.
(b) The distribution of household spending in this
small city is heavily skewed to the right. Explain
why the Normal/Large Sample condition is met in
this case
(c) The Palue of the test is 0.128. Interpret this value.
What conclusion would you make

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

The table represents a linear function. what is the slope of the function? –6 –4 4 6

Me on this one i will give you 20pts. answer should be in detail . this is the discussion topic. one of the most fiercely debated topics in sports is the hot hand theory. the hot hand theory says that success breeds success. in other words, rather than each shot a basketball player takes or each at-bat a baseball player has being an independent event, the outcome of one event affects the next event. that is, a player can get hot and make a lot of shots in a row or get a lot of hits in a row. the hot hand theory, however, has been shown to be false in numerous academic studies. read this article, which discusses the hot hand theory as it relates to a professional basketball player. state whether you agree or disagree with the hot hand theory, and give reasons for your opinion. be sure to use some of the terms you’ve learned in this unit, such as independent event, dependent event, and conditional probability, in your answer.
