l: Question 4 1.25 pts From 1995 - 2008 in the US 648 people were struck by lightening. 117 of them were women. You want to see if this observation differs from the null hypothesis, that 50% of people who are hit by lightening would be women, based on the proportion of women in the population as a whole. What would be the mean for the number of women struck by lightening in the null distribution? (round to whole number) What would be the standard deviation of the null distribution for the number of women struck by lightening? (round to one decimal) C Question 5 1.25 pts The probability that a randomly drawn measurement from a normal distribution will be within one standard deviation of the mean is approximately [x]. D Question 6 1.25 pts According to central limit theorem, increasing the sample size will result in a frequency distribution of means that is 0 normal 0 bimodal C) more similar to the actual distribution of the population D Question 7 1.25 pts What proportion of a normal distribution is within two standard deviations of the mean? 0 95% o 68% o 75% O 50%
