In the 2010 general social survey, 17% of americans said that they had no religious preference. in other words, they said they had "no religion" rather than being protestant, catholic, jewish, or another religion. in 2014, the general social survey sampled 2,538 americans and found that 21% of those surveyed said that they had no religious preference. the resulting p-value is 0.0003; thus, the null hypothesis is rejected. it is concluded that there has been an increase in the proportion of americans who have no religious preference between 2010 and 2014. what type of error is possible in this situation?

a. type i
b. type ii
c. neither
d. both

Find the volume of the solid obtained by rotating the region enclosed by the curves y=1x and y=7^-x about the x-axis. (use symbolic notation and fractions where needed.) volume =

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
