Variance
Random Processes and Relative Frequency Part 1: A fair coin is tossed repeatedly. The graph represents the relative frequency of heads that occur (number of heads divided by the total number of tosses) versus the number of times the coin was tossed for the first 10 tosses. The table shows these values, and in addition, the total number of heads after each number of tosses. Use this information to answer the questions below.

Textbook: Statistics for the Behavioral SciencesGregory J. Privitera Summarizing Data: Central Tendency - Please show your work A cognitive psychologist was interested in the ability of men and women to multitask—a cognitive skill thought to engage short-term or working memory. The psychologist observed a sample of 5 men (n = 5) and 8 women (n = 8) and measured the number of tasks they could accurately complete within a short time frame. He found that men completed 2.3 tasks on average (M = 2.3), whereas women completed 4.5 tasks on average (M = 4.5). What is the weighted mean for both samples? Hint: The overall mean is not 3.4 tasks.
