In a student club with 10 members, they want to form a committee consisting of 3 members. How many possible committee combinations are possible? (note: Since each committee member has the same role, the sequence or order does not matter, and so this is a combination problem.)

When investigating times required for drive-through service at two restaurants, the following results (in seconds) were obtained. Find the mean, median, standard deviation, range, variance, mode, and midrange for each of the two samples. (note: You should use Excel to answer these questions. Rest A Rest B 120 135 123 126 120 147 128 156 123 118 118 130 154 145 118 137 Restaurant A mean [meanA] (round to 2 decimals) median [medianA] (round to 1 decimal) standard deviation [stdevA] (round to 2 decimals) range [rangeA] (round to 0 decimals – whole number) variance [varianceA] (round to 2 decimals) mode (enter “none” if no mode), or enter the number of a single mode, or enter multiple modes (separate numbers with a comma) [modeA] (round to 0 decimals – whole number) midrange [midrangeA] (round to 1 decimal) Restaurant B mean [meanB] (round to 2 decimals) median [medianB] (round to 1 decimal) standard deviation [stdevB] (round to 2 decimals) range [rangeB] (round to 0 decimals – whole number) variance [varianceB] (round to 2 decimals) mode (enter “none” if no mode), or enter the number of a single mode, or enter multiple modes (separate numbers with a comma) [modeB] (round to 0 decimals – whole number) midrange [midrangeB] (round to 1 decimal)

Which answer best describes the complement of the event described below. Among 6 randomly selected newborn baby whales, there is at least 1 male.

For the following data, compute the z-score for the value shown, and note whether or not it is “unusual.” Round all z-scores to 2 decimal places. Answer “yes” if unusual, or “no” if not unusual (no quote marks). Answers must be exact and precise. Remember that z-scores represent how many standard deviations a value is from the mean, and any value more than 2 standard deviations either below or above from the mean is considered “unusual”. value mean std dev 95 60 12 z-score [zscore] (round to 2 decimals) Unusual? [unusual] (yes or no)

The number of calls received by a towing service follows a Poisson distribution, with an average of 26.4 calls per day (24 hour period). Find the probability that in any randomly selected hour the number of calls is exactly 2. (hint: start by finding the average calls per hour). Note: enter your answer in decimal form and round to 3 decimal places.

Assuming two possible gender outcomes among newborn baby whales (male/female), and also assuming a 50-50 probability of male or female, answer the following questions. How many possible male/female outcomes are possible among 2 randomly selected baby whales? [outcomes] What is the probability of finding only 1 female among the 2 randomly selected baby whales? (round to 2 decimal places and report as a number, not a percent) [probf] Hint: Use the Fundamental Counting Rule to find the total possible outcomes, and the Combination rule to find how many ways to get exactly a certain number of outcomes from among the larger group. Finally, divide the latter from the former to find the probability.

What is another benefit to conducting a family assessment instead of simply using an individual assessment?

For the following data, compute the z-score for the value shown, and note whether or not it is “unusual.” Round all z-scores to 2 decimal places. Answer “yes” if unusual, or “no” if not unusual (no quote marks). Answers must be exact and precise. Remember that z-scores represent how many standard deviations a value is from the mean, and any value more than 2 standard deviations either below or above from the mean is considered “unusual”. value mean std dev 110 130 12 z-score [zscore] (round to 2 decimals) Unusual? [unusual] (yes or no)
