2) 2-independent samples t-test is used to compare two samples to each other (like males to females, young to old, and so on). Enter the data in two colums in excel. In order to get the p-value, click 'data' and then 'data analysis' and then 't- test: two sample assuming equal variances. Follow the instructions provided. Value: 1 The heart rate measures collected during the lab in female students were 76,56,89,65,46,76 bpm. The heart rate measures collected in male students were 67, 68, 74,84,67 bpm. The collected data indicate that the male and female students do not exibit statictically significant difference in their heart rate. O True False Check Answer

You have reason to believe that the weekly viewing of Big Bang Theory (the television show, not the actual theory) will lower an individual's IQ. In February, seven test participants who had never watched the show were gathered, given an IQ test, subjected to weekly viewing of the show for 12 weeks, then in May given another similar IQ test. Results are as follows. Sums of interest included = 47 and 2 Σ (d-a) ² = 29.429. Participant ABCDEFG Feb 92 121 115 87 132 99 124 IQ test result May 86 118 110 78 125 91 115 4

d and f only   do not understand how to calculate     Where are the deer? Random samples of square-kilometer plots were taken in different ecological locations of a national park. The deer counts per square kilometer were recorded and are shown in the following table. Mountain Brush Sagebrush Grassland Pinon Juniper 35 17 2 30 53 6 20 19 2 26 19 8 Shall we reject or accept the claim that there is no difference in the mean number of deer per square kilometer in these different ecological locations? Use a 5% level of significance. (a) What is the level of significance? State the null and alternate hypotheses. Ho: μ1 = μ2 = μ3; H1: All three means are different.Ho: μ1 = μ2 = μ3; H1: Exactly two means are equal.    Ho: μ1 = μ2 = μ3; H1: Not all the means are equal.Ho: μ1 = μ2 = μ3; H1: At least two means are equal. (b) Find SSTOT, SSBET, and SSW and check that SSTOT = SSBET + SSW. (Use 3 decimal places.) SSTOT =   SSBET =   SSW =   Find d.f.BET, d.f.W, MSBET,…
