Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is 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 is . Assume that the groups consist of couples. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of births. The value of the mean is nothing. (Type an integer or a decimal. Do not round.) The value of the standard deviation is nothing. (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 nothing girls or fewer are significantly low. (Round to one decimal place as needed.) Values of nothing girls or greater are significantly high. (Round to one decimal place as needed.) c. Is the result of girls a result that is significantly high? What does it suggest about the effectiveness of the method? The result ▼ is is not significantly high, because girls is ▼ greater than less than equal to nothing girls. A result of girls would suggest that the method ▼ is effective. is not effective. (Round to one decimal place as needed.)

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below.the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
