Two separate samples receive two different treatments. The first sample has n=9 with M=50 and SS=710. And the second sample has n=6 with M=37 and SS=460. Are there significant treatment differences between these two samples? Use a=.05
Three treatment conditions using a sample of n = 5 in each treatment were analyzed and F was statistically significant.For this study, the three sample means are: M1 = 11, M2 =1 2, and M3 = 14. Tukey's HSD was calculated at 2.74. Were does statistical significance lie?

You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.14. You use a significance level of α=0.10α=0.10. H0:p=0.14H0:p=0.14 H1:p≠0.14H1:p≠0.14You obtain a sample of size n=345n=345 in which there are 69 successes.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null fail to reject the null As such, the final conclusion is that... The sample data support the claim that the proportion of men over 50 who regularly have their prostate examined is different from 0.14. There is not sufficient sample evidence to support the claim that the proportion of men over 50 who regularly have their prostate…

A random sample of senior citizens living in a retirement village reported that they had an average of 1.42 face-to-face interactions per day with their neighbors. A random sample of those living in age-integrated communities reported 1.58 interactions per day. Is the difference between the two senior citizen groups significant? Please provide t critical, t obtained and your decision. Retirement Community 1 Retirement Community 2 Mean1 = 1.42 Mean2 = 1.58 s1 = 0.10 s2 = 0.78 N1 = 43 N2 = 37
Are seatbelts effective at saving lives? We wish to examine whether or not the use of seatbelts reduces fatalities at the a = 0.01 level of significance. Let pN represent the proportion of non-seatbelt wearing passengers who were involved in a crash and died and py represent the proportion of seatbelt wearing passengers who were involved in a crash and died. NOTE: The data used in this study were obtained through observational study...no experiment was conducted! Which would be correct hypotheses for this test? O Ho:PN = pY, H1:PN > pY Ho: PN = pY, H,:PN Py In a random sample of 321 non-seatbelt wearing passengers involved in a car crash, 30 were killed.

Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of three comparison treatments. Each participant takes the assigned medication and his or her systolic blood pressure is recorded after 6 months on the assigned treatment. The data are shown in Table 7–58. Is there a difference in mean systolic blood pressure among treatments? Run the appropriate test at α = 0.05.
