A study by Southpaw University claims that left-handed people are more inclined to have increased intelligence levels than their right-handed counterparts. In an attempt to dispute this claim a researcher sampled individuals who have I.Q. scores exceeding 140 (the level which is commonly accepted to classify someone as a "genius") and recorded their dominant hand. 10% of the world is left-handed. Based on the sample below, at a 1% level of significance, is there evidence that a higher proportion of geniuses are left-handed than the 10% seen in the world's general population.

BLANK #2: Which type of distribution should be used to calculate the probability for this question? ***ANSWER "NORMAL", "T", OR "BINOMIAL" (WITHOUT THE QUOTATION MARKS)***

BLANK #3: Which of the following options are the appropriate hypotheses for this question: ***ANSWER WITH THE CORRECT LETTER,WITHOUT ANY QUOTATION MARKS OR BRACKETS***

A) H0: = 10% H1: > 10%

B) H0: = 10% H1: < 10%

C) H0: = 10% H1: 10%

D) H0: p = 10% H1: p > 10%

E) H0: p = 10% H1: p < 10%

F) H0: p = 10% H1: p10%

BLANK #4: What is the p-value of this sample? ***ANSWER TO 4 DECIMALS, BE SURE TO INCLUDE LEADING ZERO, EXAMPLE "0.1234"...NOT ".1234"***

BLANK#5: At a 1% level of significance, is there evidence that a higher proportion of geniuses are left-handed than the 10% seen in the world's general population? ***ANSWER "YES" OR "NO" (WITHOUT THE QUOTATION MARKS)***
