Answer #1

Answer:

Significant difference

Explanation:

For the given two sample t test for the difference between two population means, we are given

Test statistic = t = 7.04

Critical value = 2.36

So, we have test statistic greater than the critical value.

So, we reject the null hypothesis.

So, there is sufficient evidence to conclude that there is significant difference between the two population means.

    These two groups are two samples representing the population of workers in the economy. We want to know if the workers who take the training (treatment sample) have higher earnings than the group that do not take the training (control sample). If we find that the trained workers have higher earnings it would indicate that the training is effective.[1]In terms of statistics, we will do a hypothesis test on the difference between the mean earnings in the treatment population and...

    A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 16 nursing students from Group 1 resulted in a mean score of 41.3 with a standard deviation of 2.5. A...

    Vampire bats are a model group for understanding social behaviours, altruism and "morality". This is because they share blood meal (by regurgitating some of the blood they consumed) with other bats who were not able to feed that night. This is important because if a bat misses as little as two nights worth of dinners they starve to death. Bats that have shared a meal with another bat recently are more likely to be helped in return. A researcher is...
