Question

The test is left-tailed.

Based on a sample of 60 men, 30% owned cats
Based on a sample of 80 women, 35% owned cats

The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)

Based on this we fail to reject the null hypothesis.

A researchers is interested in the amount of sleep an individual receives after consuming a sleeping aid (Melatonin, Valerian root, and Placebo). The researcher randomly selects individuals into either group. However, some individuals drop out of the study which results in unequal sample sizes.

I need help asap. This is the question. A recent study at a local college claimed that the porportion, p, of students who commute more than 15 miles to school is no more than 15% . If a random sample of 175 students at this college is selected, and it is found that 86 commute more than 15 miles to school, can we reject the college's claim at the 0.05 level of significance.

A postgraduate student studying genetics at Copper belt University was attempting to cross a tiger and a cheetah. He predicted a phenotypic outcome of the traits he was observing to be in the following ratio 4 stripes only: 3 spots only: 9 both stripes and spots. When the cross was performed and he counted the individuals she found 50 with stripes only, 41 with spots only and 85 with both. According to the Chi-square test, did he get the predicted outcome? In your answer include; A possible null hypothesis (H0) that the engineer might have proposed. Clearly show your workings.

Suppose you conduct a hypothesis test based on a sample where the sample size is n = 50, and arrive at a p-value of 0.08. You then refer back to your notes and discover that you made a careless mistake, the sample size should have been n = 500. Will your p-value increase, decrease, or stay the same? stay the same increase decrease Answer not here
