The null hypothesis is that those attending boot camo have a recidivisme of 355 303 Complete parts through) below What is the sample proportion of successes? Ot is somewhat odd to call returning to prison asco ) De 030 Type anger or a decimal Do not found) b. What is the hypothetical proportion of success under the nullhypothesis? Po - 035 (Type an integer or a decimal Do not round) What is the value of the best it? Explain content 2 -104 Round to two deca glaces as needed) The value of the test t estate observed proportion Round to two decal places as needed) one was 0.30 standard rom above the nail hypothesis proportion of poners 7 8 9 0 Backpace Munk

Answer 1

Ho: P=0.35 p=0.30 TestStatisitc 2 0.3-0.35 = -1.05 0.35(0.65) V 100 The observed proportion is 1.05 standard deviation below the null hypothesis proportion It is below because ti is negative
