Ahusband and wife, ed and rena, share a digital music player that has a feature that randomly selects which song to play. a total of 3476 songs have been loaded into the player, some by ed and the rest by rina. they are interested in determining whether they have loaded different proportions of songs into the player. suppose that when the player was in random-selection mode, 34 of the first 50 songs selected songs were loaded by rena. let "p" denote the proportion of the songs that were loaded by rina.
a) state the null and alternative hypothesis to be tested. how strong is the evidence that ed and rina have loaded different proportions of songs into the player? make sure to check the conditions for the use of this test.
b)are the conditions for the use of the large sample confidence interval met? if so, estimate with 95% confidence the proportions of the songs that were loaded by rina.

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
