Carlos notices he usually pushes the clear button on his calculator more than once each time he wants to clear the screen. Carlos’ teacher suggests that about 20% of all students have this habit, but Carlos thinks it might be greater. He randomly selects 100 students in his school and finds that 25 of them push the clear button more than once. To determine if these data provide convincing evidence that the proportion of students who push the clear button more than once is greater than 20%, 100 trials of a simulation are conducted. Carlos is testing the hypotheses: H0: p = 20% and Ha: p > 20%, where p = the true proportion of students who push the clear button more than once. Based on the results of the simulation, what is the estimate of the P-value of the test? 11%
17%
20%
25%

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
