The average amount of time it takes for couples to further communicate with each other after...

The average amount of time it takes for couples to further communicate with each other after their first date has ended is 3.07 days. Is this average different for blind dates? A researcher interviewed 52 couples who had recently been on blind dates and found that they averaged 3.4 days to communicate with each other after the date was over. Their standard deviation was 0.837 days. What can be concluded at the the α = 0.10 level of significance? For this study, we should use The null and alternative hypotheses would be: H 0 : H 1 : The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is α Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the population mean is not significantly different from 3.07 at α = 0.10, so there is enough evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is equal to 3.07. The data suggest the populaton mean is significantly different from 3.07 at α = 0.10, so there is enough evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is different from 3.07. The data suggest that the population mean is not significantly different from 3.07 at α = 0.10, so there is not enough evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is different from 3.07.

Suppose you are interested in measuring the amount of time, on average, it takes you to make your commute to school. You've estimated that the average time is 35.68 minutes with a standard deviation of 6.17 minutes. Assuming that your estimated parameters are correct and the commute time is normally distributed, what is the probability that the average commute time of 11 random days is greater than 36.86 minutes?

A scooter company wants to determine the average amount of time it takes an adult to assemble an “easy to assemble” scooter. A sample of 49 times yielded an average time of 18.15 minutes. Assume that the assembly times are normally distributed and the population has a standard deviation of 5.39 minutes. a) Give a point estimate for the population mean that the sample of data is taken from. b) Find the 96% confidence interval for the mean assembly time.

1. There are two players. Each names an amount at the same time as the other. They can say $0 or say $10 or anything in between, even fractions of cents. If the amounts total $10 or less they get what they named. If they total more than $10 they get $0. What are the Nash equilbria? To solve this try some pairs of amounts. If they aren’t equilibria – if one player or both could do better by changing...
