we can not do t test. here only counts . The t test we can use the numerical values not an count.
if you have 60 who love chevy trucks and 24 people who love ford trucks, can you do a t-test hypothesis with this data. if so, how?
You believe that people who have higher GPAs began smoking marijuana in younger grades. You want to test this hypothesis. Identify the independent and dependent variables and develop a hypothesis. What is the best SPSS test based on your hypothesis to analyze your data? Would you choose a t-test, a double t-test, an ANOVA, or a chi-square?
Can you identify five “survivor sites” websites for people who loss love ones? Give a summary of the information to be found on each site.
How do you solve for the P-value? In a hypothesis test with hypotheses Ho : j < 54 and H1 :u > 54, a random sample of 24 elements selected from the population produced a mean of 59.0 and a standard deviation of 14.0. The test is to be made at the 2.5% significance level. Assume the population is normally distributed. What is the critical value of t? 1.96 02.064 • 2.069 -2.069 What is the value of the test...
Do biases in developmental pathways limit evolutionary possibilities? how can you test this hypothesis?
a study is conducted to test the hypothesis that people with glaucoma have higher than average blood pressure. the study includes 30 people with glaucoma whose mean bp is 140 mm hg with a standard deviation of 24mm hg. the distribution of sbp appears to be bell shaped. you need to construct a 95% confidence interval for the true mean sbp among people with glaucoma. to help you do so, answer each of the following questions. What is the standard...
You decide to test this screening test on a larger population, so you find 235501 people who agree to be tested and 5849 people test positive. Given this information, you can determine the prevalence of disease in the population you studied. Report this in whole cases per 1000 persons per year.
ONLY DO NUMBER 3 For this project you will test claims and conjectures using hypothesis testing. For each hypothesis test, report the following: The null hypothesis, H0 The alternative hypothesis, H1 The test statistic rounded to the nearest hundredth (use T Stats or Proportion Stats in StatCrunch to find test statistics) The P-value for the test (use T Stats or Proportion Stats in StatCrunch to find P-values) The formal decision (Reject H0 or Fail to reject H0, remember that reject...

You conduct the following hypothesis test using the Spring Break 2020 data of GVSU students who went to Florida during spring break: Ho: mu >= $675 Ha: mu < $675 The test statistic value is t = -3.31. What is the p-value for this test? Round to 3 decimal places.
You want to know whether people who power-pose feel more confident than those who don't. To answer this question, you ask 50 people to power-pose, then rate how confident they are (from 0 to 11) where higher is more. You also ask 50 other randomly picked individuals to rate how confident they are without power-posing. This data is in the file "power_posing.txt". The first column represents the confidence ratings, the second column whether they power-posed (1) or not (0). What...
