Question

Does it take a different amount of time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 53 seeds that were exposed to rock music took an average of 28 days to germinate. The standard deviation was 11 days. The 40 seeds that were exposed to classical music took an average of 32 days to germinate. The standard deviation for these seeds was 11 days. What can be concluded at the αα = 0.05 level of significance?

1. For this study, we should use Select an answer z-test for a population proportion z-test for the difference between two population proportions t-test for the difference between two independent population means t-test for a population mean t-test for the difference between two dependent population means
2. The null and alternative hypotheses would be:   
3.   

H0:H0:  Select an answer p1 μ1  ? < = ≠ >  Select an answer μ2 p2  (please enter a decimal)   

H1:H1:  Select an answer p1 μ1  ? ≠ < = >  Select an answer p2 μ2  (Please enter a decimal)

3. The test statistic ? z t  =  (please show your answer to 3 decimal places.)
4. The p-value =  (Please show your answer to 4 decimal places.)
5. The p-value is ? ≤ >  αα
6. Based on this, we should Select an answer accept reject fail to reject  the null hypothesis.

Answer 1

a) t-test for the difference between two independent population
