1. Question: .Jamie, a bowler, claims that her bowling score is less than 168 points, on average. Several of her teammates do not believe her, so she decides to do a hypothesis test, at a 1% significance level, to persuade them. She bowls 17 games. The mean score of the sample games is 155 points. Jamie knows from experience that the standard deviation for her bowling score is 19 points. H0: μ≥168; Ha: μ<168 α=0.01 (significance level) What is the test statistic (z-score) of this one-...

1. Question: A data set is summarized in the frequency table below. Using the table, determine the number of values less than or equal to 5. Give your answer as a single number. For example if you found the number of values was 19, you would enter 19. 2. Question: Given the frequency table, how many times does the data value 3 show up in the data set? 3. Question: A group of students were surveyed about the number of siblings they have. The frequencies and relative frequencies of their responses...

A growing concern in agricultural and food chemistry is the presence of residues in food. Weuse many forms of organic chemicals in agriculture and food chemistry and there is growingconcern as to how safe these materials are. Choose an organic chemical used in agricultural offood chemistry and report on the functional groups contained in your compound, the uses of thecompound, and the safety of that compound. This research will require one or more outsidesources. Ensure all citations are in APA ...
