Accepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces(e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation). NOTE: For scientific notation,a period MUST be used as the decimal point marker.Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values.For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.Q-Mart is interested in comparing its male and female customers. Q-Mart would like to know if the amountof money spent by its female charge customers differs, on average, from the amount spent by its malecharge customers. To answer this question, an analyst collected random samples of 25 female customersand 22 male customers.Based on these samples, on average, the 25 women charge customers spent $102.23 and the 22 mencharge customers spent $86.46. Moreover, the sample standard deviation of the amount charged by the25 women was $93.393, and the sample standard deviation of the amount charged by the 22 men was$59.695.Suppose, using a 10% level of significance, you wish to know if there is sufficient evidence for Q-Mart toconclude that, on average, the amount spent by women charge customers differs from the amount spentby men charge customers. That is suppose you wish to test
