Past records from a local hospital stated that the proportion of full-term babies born in the hospital who weigh less than seven pounds is 40%, Suppose that wehave strong reason to believe the proportion is greater than 40%, and we wish to carry out a hypothesis test. State the null hypothesis H and the alternativehypothesis H, that we would use for this test.Ho: 0H;: 0O

The table below shows results from a recent General Social Survey on two variables, respondent sex and whether one believes in an afterlife. Compare the proportions of women and men who believe in an afterlife. Question: State the hypotheses, calculate the test statistic, p-value and write your conclusions, using α = 0.05. Belief in Afterlife Sex Yes No or Undecided Total 1. Male 375 134 509 2. Female 435 147 582 Let = 1. be the population proportion of men who believe in an afterlife Let = 2. be the population proportion of women who believe in an afterlife

Consider the following hypothesis test: Ho : μ > 45 Ha : μ < 45 A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results. Use a = 0.01, a. With 44 and s= 5.2, the p-value is less than 0.005 Can it be concluded that the population mean is less than 45 ? No b. With = 43 and s= = 4.6, the p-value is between 0.01 and 0.025 ✓ Can it be concluded that the population mean is less than 45? Yes c.

You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. Ho: μ ≥ 40 Hg: μ < 40 A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results. Use a = 0.01. (a) x = 39 and s = 5.1 Find the value of the test statistic. (Round your answer to three decimal places.) -1.18 X Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Reject Ho. There is insufficient evidence to conclude that μ< 40. Do not reject Ho. There is insufficient evidence to conclude that u < 40. Do not reject Ho. There is sufficient evidence to conclude that μ < 40. Reject Ho. There is sufficient evidence to conclude that μ < 40. (b) x = 38 and s = 4.6 Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. Reject Ho. There is insufficient evidence to…
