Note: ALL null hypotheses include an equal sign. For the alternative APPENDIX A hypothesis, there can be three possibilities, which can be any of the following. Cumulative a. The population parameter is not equal to the claimed value. (TWO- robability TAILED TEST) Cumulative probability for z is the area under the b. The population parameter is greater than the claimed value. (RIGHT- standard normal curve to the left of TAILED TEST) c. The population parameter is less than the claimed value.

The General Manager of Sariwang Lamig refrigerators tells an investigative reporter that 90% of its customers are satisfied with their overall purchasing experience. What hypothesis will be used by the reporter to test the claim? TABLE A Standard Normal Cumulative Probabilities (continued) 4. A researcher claims that class A which is exposed to a particular instructional teaching approach has higher mean test score than class B which is exposed to conventional teaching approach. What hypothesis will be used to test the claim? II. Perform the hypothesis test. 1. A random sample of 100 recorded crocodile deaths in four crocodile farms in Visayas and Mindanao during the past year showed an average life span of 71.8 years. Assuming a population standard deviation of 8.9 years, does this seem to indicate that the mean life span of crocodiles in captivity is greater than 70 years? Use a 0.05 level of significance. 99999713
