Question 18 2 Points The average weight loss in following the ketogenic diet after 30 days of strict compliance is 6 kilograms. In order to boost the effect, 16 male adults combined this diet with intermittent fasting 3 days a week. The result shows an average weight loss of 8 kilograms with a standard deviation of 3 kilograms. Is there enough evidence to show that combining ketogenic diet with Intermittent fasting is more effective? Describe the test of hypothesis to use. A Right - talled test; t - distribution B Left - tailed test; f - distribution c ) Left - tailed test; z - distribution D Right - talked test; z - distributionQuestion 17 2 Poi The average weight loss in following the ketogenic diet after 30 days of strict compliance is 6 kilograms.

A researcher conducted a survey in Baguio City and selected 25 respondents and measured their daily Vitamin C intakes. If the group consumed an average of 81 grams per day with a standard deviation of 10 grams per day, is it valid to conclude at 0.05 level of significance, that the female adolescent of this age group from this City consume more than Vitamin C per day than the recommended consumption? Determine the test distribution to use, and the type of test. t-distribution / left tailed test B two-tailed test c ) t- distribution / right tailed test D) z-test / right taled testQuestion 19 2 Points The average IQ of a particular set of Grade 11 students is 110 with a standard deviation of... 20. In the advent of a sudden change in the school set-up, a researcher claimed that this has changed. To test the claim, 30 randomly selected students were taken and was found to have a mean IQ of 100. Compute for the p-value associated with the sample taken. A 0.0052 B 0.0061 C 0.0031 D 0.0104
