Please help me solve this statistics problem from my lecture. Thank you.
We believe that 77% of the population of all Business Statistics students consider statistics to be an interesting topic. Suppose we randomly and independently select 24 students from the population. If the actual percentage is really 77%, find the probability of observing 23 or more students who find statistics to be an interesting topic. Round to six decimal places.
A study was conducted to examine the impact of speaking in public on college students. A class of 15 statistics students participated in the study. At the beginning of a lecture the students recorded their systolic blood pressure. During the lecture the instructor called on each student to stand and answer questions about topics in the lecture. After speaking the students once again recorded their blood pressure. The resulting values are given below along with summary statistics. before 100 123 128 125 136 108 130 113 105 136 146 138 108 149 132 after 141 142 146 136 144 111 132 114 103 133 140 130 100 133 113 difference -41 -19 -18 -11 -8 -3 -2 -1 2 3 6 8 8 16 19 before after difference mean 125.1 127.9 -2.733 st dev 15.26 15.45 15.23 Does this information indicate that blood pressure increased because of speaking?
