Please make sure the hypothesis is set up like this:Ho: Mew = valueH1: mew < or > valuefor h1 I'm stuck on whether it is less than or greater than. **Statistical Analysis of Reaction Times in Older Women****Study Summary:** A group of twenty-five women aged between 70 and 80 were randomly selected to participate in a special program aimed at decreasing reaction time. Upon completion of the course, these women exhibited an average reaction time of 688 milliseconds. For comparison, the mean reaction time for the general population of women in this age bracket is known to be 750 milliseconds, with a standard deviation of 300 milliseconds.**Tasks for Analysis:**(a) **Compute a 95% Confidence Interval:** - Calculate the 95% confidence interval for $ \mu $, the population mean reaction time, for women who have taken part in the program.(b) **Conduct a Hypothesis Test:** - Determine whether the educational course had a statistically significant effect on the reaction times by performing a hypothesis test.This exercise will enable students to apply statistical concepts such as confidence intervals and hypothesis testing to real-world scenarios, enhancing their understanding of statistical analysis methods.

O1h 29m Remaining 8.MCTQ Section Exercise 1 A hypothesis test is to be performed. Determine the null and alternate hypotheses. dlo In 1991, the average duration of long-distance telephone calls originating in one town was 6.9 minutes. A long-distance telephone company wants to perform a hypothesis test to determine whether the average duration of long-distance phone calls has changed from the 1991 mean of 6.9 minutes.

MORE BENEFITS OF EATING ORGANIC Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data. In this case, we are testing Họ : Po = Pc Ha: Po > Pc where p, and p. represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. Use a 5 % significance level. Effect of Organic Bananas After 25 Days After 25 days, the proportion of fruit flies eating organic bananas still alive is 0.45 , while the proportion still alive eating conventional bananas is 0.42. The standard error for the difference in proportions is 0.029. What is the value of the test statistic? Round your answer to two decimal places. z = i What is the p-value?

One of the advantages of understanding statistics is that you can apply the concepts to yourself. This is even easier to do during our present time because of the widespread use of wearables. Wearables are accessory devices or clothing with embedded technology that are worn by a person and used to provide feedback to the person wearing them. Examples include the Fitbit, which is worn on the wrist and gathers data such as number of steps walked, heart rate, sleeping time. Another example is Ambiotex's smart shirt which is designed for athletes and has sensors in the shirt to measure heart rate, anaerobic threshold, fitness and stress levels. There are other companies making similar products. Suppose that you are interested in the amount of sleep you get a night. Sleep is very important and there is evidence that many Americans do not get enough sleep. You hypothesize you get 6 hours of sleep a night. Using a wearable, you track your amount of sleep on 16 random nights. Test the…

Before the furniture store began its ad campaign, it averaged 222 customers per day. The manager is investigating if the average is smaller since the ad came out. The data for the 14 randomly selected days since the ad campaign began is shown below. Round your mean and standard deviation to three decimal places when doing these calculations. 224, 211, 206, 206, 232, 189, 222, 197, 220, 210, 212, 213, 208, 189 Download CSV Assuming that the distribution is normal, what can be concluded at the a = 0.01 level of significance?
