Answer all please

\"We are conducting a hypothesis test with the following hypotheses: Ho: p=25, Ha: p25, which cf the followingw represent a Type l Error? 0 We fail to reject the null hypothesis when, in fact, p is not 25. Q We reject the null hypothesis when, in fact, p is not 25. Q We fail to reject the null hypothesis when, in fact, [.1 is actually 25. Q We reject the null hypothesis when, in fact, p is actually 25. 27 of50 Acalculated value of d = .45 indicates O a small effect size 0 a medium effect size 0 a large effect stze O a significant effect size 28 of 50 Statistical power is the probability of O rejecting the null when it is false. 0 making a Type I error. 0 rejecting the null when it is true. 0 making a Type II error. When testing for differences between the means of two related populations, what is the null hypothesis? 0 The difference between the population means is equal to 0. O The difference between the population means is equal to 'i. O The difference between the population means is greater than 1. O The difference between the population means is greater than 0. 30 of 50 Why do we use the tdistribution instead of the normal distribution as our reference distribution? 0 The population variances are unknown and we are estimating them from a sample. 0 You never use the normal distribution in applied statistics. 0 Because our sample size is large. Q Since we are using the standard deviation instead of the variances in our calculations, ., \\ .._. 29 of50 '\"" uld
