- What is the purpose of the Intermediate Value Theorem?. One of the assumptions of one-sample t-test is that the dependent variable and the independent variable must be continuous (interval/ratio). A. TrueB. FalseC. None of the above choicesWhich of the following statements about interval estimates is NOT TRUE? A. The interval estimate may or may not contain the value of the parameter being estimated B. The confidence level of an interval estimate of a parameter is the probability that the interval estimate is equal to the point estimate C. When the sample size is large, approximately 95% of the sample means fall within 1.96 standard deviations of the population means. D. The formula for getting the interval estimate is equal to point estimate +, - the product of the critical value and standard error E. Interval estimates are prefered over pont estimates since a confidence level can be specified
- The sample mean is Greater/Less than the previous mean, so, on average, consumption from the sample is Greater/Less than in the previous study. The sample standard deviation is Greater/Less than the previous standard deviation by _____ so the milk consumption is More/Less spread out in the sample. Above is the complete question for the last question of the problem that I attached below.1) The sum of observed frequencies is always _____ the sum of the expected frequencies. * A equal to B less than C greater than 2) Which of the following cannot be a value of chi-square? * A 0 B 1 C -1 3) Local government officials, whether pro or anti-administration, where asked about the government's policy to issue a preventive suspension order. Is it fair? What kind of chi-square test was used? * A Test of Independence B Test of Homogeneity C Test of Goodness of Fit 4) The Chi-square test is a____. * A non-parametric test B parametric test C none of theseThe claim is that the proportion of adults who smoked a cigarette in the past week is less than 0.250.25, and the sample statistics include nequals=18171817 subjects with 400400 saying that they smoked a cigarette in the past week.

Which of the following is the MOST appropriate conclusion he could draw? Group of answer choices The SAT scores for the three groups are all different from each other. No conclusion can be determined without conducting further analyses. The SAT scores for the three groups are not significantly different. The SAT scores for the three groups are all equal to each other.Formulate the null and alternate hypotheses for the following situations.
