ssume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This methe designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl s 5. Assume that the groups consist of 39 couples. Complete parts (a) through (c) below. . Find the mean and the standard deviation for the numbers of girls in groups of 39 births. The value of the mean is u = 19.5. Type an integer or a decimal. Do not round.) The value of the standard deviation is o = 3.1 (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of girls or fewer are significantly low. (Round to one decimal place as needed.) Values of girls or greater are significantly high. (Round to one decimal place as needed.) c. Is the result of 29 girls a result that is significantly high? What does it suggest about the effectiveness of the method? The result V significantly high, because 29 girls is girls. A result of 29 girls would suggest that the method (Round to one decimal place as needed.) Enter your answer in each of the answer boxes. P Type here to search

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
