Are you smarter than your older brother? In a study of birth order and intelligence, IQ tests were given to 18- and 19-year-old men to estimate the size of the difference, if any, between the mean IQs of firstborn sons and of secondborn sons. The following data for 10 firstborn sons and 10 secondborn sons are consistent with the means and standard deviations reported in the article. It is reasonable to assume that the samples come from populations that are approximately normal. Can you conclude that the mean IQ of firstborn sons is less than the mean IQ of secondborn sons? Let mu, denote the mean IQ of firstborn sons and mu2 denote the mean IQ of secondbor sons. Use the alpha = 0.05 level and the P-value method with the TI-84 Plus calculator. Firstborn
107 113 84 126 99
95 98 109 91 90
Secondborn
112 92 102 86 97
106 105 116 109 95

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

yes, i heard the "tea" with james charles and a few other beauty gurus. i believe charles is in the wrong and i believe tati the most. tati didn't lie about james charles but may have exaggerated because he never sexually assaulted anyone. jeffery star is a really good friend to all and out anyone that needs it, until you mess with one of his "sisters"! james will never rise over jeffery or tati, he's way to sensitive and dramatic to rise about them. i think all three of them will make up and be friends again because they always get over it.

i hope this with your
