It is claimed that if parents use the UCHOOS method of gender selection there is a greater than 50% chance of have a girl. Determine the true proportion using a 95% confidence. Assume the sample data consist of 56 girls born in 105 births. A random sample of 19 green M&Ms has a mean of .8635 grams and a standard deviation of .057 grams. Test the claim that the mean weight of all green M&Ms is different than .8535 grams. Assume an alpha value of .05.

XSORT Method of Gender Selection When testing a method of gender
selection, we assume that the rate of female births is 50%, and we
reject that assumption if we get results that are unusual in the
sense that they are very unlikely to occur with the 50% rate. In a
preliminary test of the XSORT method of gender selection, 14 births
included 13 girls. Assuming a 50% rate of female births, find the
probability that in 14 births, the number...

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 0.5. Assume that the groups consist of 44
couples. Complete parts A to C below.
