The number of chocolate chips in an 18 ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and a standard deviation 129 chips. a. The probability that a randomly selected bag contains between 1100 and 1400 chocolate chips, inclusive, is (Round answer four decimal places as needed)b. The probability that a randomly selected bag contains fewer than 1100 chocolate chips is (Round answer four decimal places as needed).c. The probability that a randomly selected bag contains more than 1225 chocolate chips is (Round answer four decimal places as needed).d. A bag that contains 1000 chocolate chips is in the percentile (Round answer to the nearest integer as needed).

Ten members of balin's soccer team ran warm ups for practice. each member ran the same distance. their combined distance was 5/6 of a mile. to find the distance that each member ran, balin wrote the expression below.

X+ 4y − z = −14 5x + 6y + 3z = 4 −2x + 7y + 2z = −17

For a research project in a political science course, a student has collected information about the quality of life and the degree of political democracy in 50 nations. specifically, she used infant mortality rates to measure quality of life and the percentage of all adults who are permitted to vote in national elections as a measure of democratization. her hypothesis is that the quality of life is higher in more democratic nations. read this research description carefully. pay attention to the following: how many variables are in this research? what is the scale of the variable for infant mortality? p1c4. what is the dependent variable in this research problem? p1c4. is this research descriptive or inferential? does this research involves single variable analysis or two or more variable analysis?
