4. A researcher believes that the proportion of a community’s population in favor of a new park is greater than the countywide proportion of 0.65. A survey of 67 people in the community reveals that the estimated proportion of the community in favor of it is equal to 0.76. Use alpha = 0.05. State the null and alternative hypotheses, find the test statistic, compare it with the critical value, make a decision, and find the p-value.

A researcher believes that community B has a lower income than community A. Forty people are surveyed in each of the two communities regarding their income. In place A, the mean among the 40 individuals is 62 (given in thousands; you can ignore the ‘thousands’ and just use ‘61’), and the variance is 95; in place B, the mean among the 40 surveyed is 59, and the variance is 100.   Test the null hypothesis that the two communities have equal...

The mean number of shopping trips per week in a county is 2.2. In a particular neighborhood within the county, a survey based on 50 people reveals that the mean in the neighborhood is 1.85, with a standard deviation of 1.2. Test the null hypothesis that the mean in the neighborhood is no different from that in the county. State the null and alternative hypotheses, find the test statistic, compare it with the critical value, make a decision, and find...

A survey of n = 50 people reveals that the proportion of residents in a community who take the bus to work is 0.15. Is this significantly different from the statewide average of 0.10? Use a significance level of 0.05. Write down the null and alternative hypotheses, find the test statistic and the p-value, and state your conclusion.

A researcher claims that 25% of people in the U.S. population have circulation problems. In a random sample of 189 people, 38 had circulation problems. Test at the alpha = 0.05 significance level to see if the percent is 25% or if it is less. You should give your null and alternative hypotheses, then decide if you accept or reject the null hypotheses (find the test statistic and either the P-value or critical value(s)).

C. A researcher uses ANOVA to test 4 groups with n=13 in each group and obtains an F=2.85. Is this value sufficient to reject the null with alpha = 0.05? Provide the degrees of freedom values, the critical region value, and your decision regarding the null hypothesis. Put your final answer in APA format D. Is this value (F= 2.85) Sufficient to reject the null with alpha 0.01? provide the degrees of freedom values, the critical region value, and your...
