Suppose the average life expectancy of someone with diabetes is u = 70 years, 0' = 10. Suppose that a sample of n = 64 people diagnosed with diabetes who received a blood glucose monitoring implant had an average life expectancy of M = 74 years. Assuming a two-tailed test with or = .05, what is the Z- score for this sample? In a one-sample t-test with sample size n = 12, observed statistic t = -1.41, and estimated standard error sM = 4.14, find the effect size in terms of proportion of variation explained. -0.3406 0.1105 0.1047 0.0995Suppose a population has variance 01 = 5. If we multiply every score in the population by -2, what will the new variance be? Choose the closest
