The average amount of time it takes for couples to further communicate with each other after their first datehas ended is 3.77 days. Is this average different for blind dates? A researcher interviewed 61 couples who hadrecently been on blind dates and found that they averaged 3.9 days to communicate with each other after thedate was over. Their standard deviation was 1.477 days. What can be concluded at the a = 0.05 level ofsignificance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Но:Select an answer OH1:Select an answerc. The test statistic ? O -(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is > 8 af. Based on this, we should acceptg. Thus, the final conclusion is that ...e the null hypothesis.The data suggest that the population mean is not significantly different from 3.77 at a = 0.05, sothere is statistically insignificant evidence to conclude that the population mean time for coupleswho have been on a blind date to communicate with each other after the date is over is differentfrom 3.77.The data suggest the populaton mean is significantly different from 3.77 at a = 0.05, so there isstatistically significant evidence to conclude that the population mean time for couples who havebeen on a blind date to communicate with each other after the date is over is different from3.77.O The data suggest the population mean is not significantly different from 3.77 at a = 0.05, sothere is statistically significant evidence to conclude that the population mean time for coupleswho have been on a blind date to communicate with each other after the date is over is equal to3.77.

a) The population standard deviation is unknown. Thus, we should use one sample t test for mean.

Part 1 of 4 Victoria, an accomplished marathon runner, claims that the standard deviation for her time to run a 26.2 mile marathon is less than 17.5 minutes. To test her claim, Victoria looks up 11 of her race times (in minutes): 227.2, 233.3, 259.7, 265.8, 252.1, 228.8, 222.6, 202.9, 214.5, 237.2, 267.7 Perform a hypothesis test using a 9% level of significance to test Victoria's claim. Step 1: State the null and alternative hypotheses. 17.5 Ha:0
Russell is doing some research before buying his first house. He is looking at two different areas of the city, and he wants to know if there is a significant difference between the mean prices of homes in the two areas. For the 39 homes he samples in the first area, the mean home price is $⁢176,400. Public records indicate that home prices in the first area have a population standard deviation of $⁢32,930. For the 32 homes he samples in the second area, the mean home price is $⁢181,500. Again, public records show that home prices in the second area have a population standard deviation of $⁢23,835. Let Population 1 be homes in the first area and Population 2 be homes in the second area. Construct a 95% confidence interval for the true difference between the mean home prices in the two areas. Round the endpoints of the interval to the nearest whole number, if necessary. Lowest Endpoint = upper Endpoint=
A researcher would like to determine if relaxation training will affect the number of headaches for chronic headache sufferers. For a week prior to training, each participant records the number of headaches suffered. Participants then receive relaxation training and for the week following training the number of headaches is again measured. The data are as follows: Participant Before After 3 3. 4 Do the results indicate a significant difference? Use a one-tailed test with a = .05 4. 2. 4. 1. 2. 4) 5.
A new drug is being tested to see if it reduces the frequency of migraines. Study participants were divided into two groups. 49 participants in group 1 received the medication; 42 participants in group 2 received a placebo. After a period of six months, group 1 had a mean of 4 migraines. It is known that the population standard deviation for this group is 1.3 migraines. Group 2 had a mean of 5.4 migraines. The population standard deviation for this group is 1.7 migraines. Can we conclude that the medication reduces the population mean number of migraines? Use αα =0.01. Note: If t-test, then unequal variances are assumed. Question a)Let: μ1μ1 = the population mean number of migraines with the medication μ2μ2 = the population mean number of migraines with the placebo (Step 1) State the null and alternative hypotheses by selecting the appropriate symbol, and identify which tailed test: H0:H0: μ1μ1 μ2μ2 H1:H1: μ1μ1 μ2μ2 Which tailed test…

In an attempt to test that claim, gave an IQ test to two groups of people: Group 1: Students who primarily listen to non-classical music. • Group 2: Students who primarily listen to classical music. Their scores are summarized in the following table: Std.

A study is done to determine if students in the California state university (CSU) system take longer to graduate, on average, than students enrolled in private universities using the significant level of 5%. One hundred students from both the California state university system and private universities are surveyed. Suppose that from years of research, it is known that the population standard deviations are 1.5811 years for CSU and 1 year for private universities. The following data are collected. The California state university system students took on average 4.5 years with a standard deviation of 0.8. The private university students took on average 4.1 years with a standard deviation of 0.3. What is the decision rule of rejecting the null hypothesis

A researcher wanted to know whether losing one night sleep can affect problem solving. A sample of n = 25 college students was given a problem-solving task at noon on one day and again at noon on the following day. The students were not permitted any sleep between the two tests. For each student, the difference between the first and the second score was recorded: MD = 5 and standard deviation of the difference score was s = 10. Do the data indicate a significant change in problem solving ability? Use a two-tailed test with α = .01. The alternative hypothesis in words is Group of answer choices Problem solving ability improves after losing on night sleep Problem solving ability is reduced after losing one night of sleep There is no significant difference in problem solving ability between the two conditions: before and after losing one night of sleep There is a significant difference in problem solving ability between the two conditions: before and after losing one night of…
Hi! I need your help. Thank you so much! A maintenance supervisor is comparing the standard version of an instructional booklet with one that has been claimed to be superior. An experiment is conducted in which 26 technicians are divided into two groups, provided with one of the booklets, then given a test a week later. For the 13 using the standard version, the average exam score was 72.0, with a standard deviation of 9.3. For the 13 given the new version, the average score was 80.2, with a standard deviation of 10.1. Using the 0.05 level of significance, what conclusion can be reached? Use Pooled-Variances T-Test.
