Is having a long, more complex first name more dignified for a girl? Are girls’ names longer than boys’ names? With current names like “Alexandra,” “Madeleine,” and “Savannah,” it certainly appears so. To test this theory random samples of seventh-grade girls and boys were taken. Let x be the number of letters in each seventh grader’s first name.
At the 0.05 level of significance, do the data support the contention that the mean length of girls’ names is longer than the mean length of boys’ names?
