A manufacturer must test that his bolts are 4.00 cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 121 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.21 cm. He knows that the population standard deviation is 0.83 cm. Assuming a level of significance of 0.02, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines? Step 3 of 3: Draw a conclusion and interpret the decision.
Test the significance at 0.05 level of the computed values of correlation r= 0.65 with a sample size of 10
Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measured in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in ₁ = 290 and s₁ = 12, and another random sample of 16 gears from the second supplier results in ₂ = 321 and s₂ = 22. Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength? Use a = 0.05, and assume that both populations are normally distributed but the variances are not equal. O a. Because -4.64 < -1.714, fail to reject the Null Hypothesis Ob. None among the choices O c. Reject the Null Hypothesis Od. Because -4.64 < -1.714, reject the Null Hypothesis
You are part of a trivia team and have tracked your team's performance since you started playing, so you know that your scores are normally distributed with u = 88 and a = 15 Recently, a new person joined the team, and you think the scores have changed Sample data is: n = 28, sample mean = 72 Assuming a two tailed test, What is the test statistic (Z)?

When should the Wilcoxon Signed-Rank test be used instead of a paired t-test?
The attached results are for a multiple regression study of smartphone addiction (SSA-SV) proneness in relation to 1) Gender 2)Age 3) Anxiety (GAD-7). I just want to clarify that age is statistically significant with p = 0.006; is this correct? What's throwing me off is the notation "< .001" on the top line under the p category. I was under the impression that the p-value would need to be less than 0.001.

A researcher is conducting a two-tailed hypothesis test (alpha=.05) among 39 adults from Omaha to examine whether there are significant differences between women and men in their views on gun control safety in Omaha. When looking at the t-table to choose a critical score, he finds that the degrees of freedom falls in-between 2 numbers. Why does he choose the higher t(critical) score, 2.042, rather than 2.021? Check all that apply a. Because choosing the higher critical score is a more liberal test. b. Because choosing the higher critical score is a more conservative test. c. Because choosing the higher critical score reduces the likelihood of Type I error. d. Because choosing the higher critical score reduces the likelihood of Type II error. e. Because choosing the higher critical score makes it easier to reject the null. f. Because choosing the higher critical score makes it more difficult to reject the null.
8 If the analysis of variance F-test leads to the conclusion that at least one of the model parameters is nonzero, can you conclude that the model is the best predictor for the dependent variable y? Can you conclude that all of the terms in the model are important for predicting y? What is the appropriate conclusion?
What is the null hypothesis for a two-tailed test of Pearson's r correlation coefficient and how is it tested using a significance level of alpha=0.05?
A psychologist has developed a standardized test for measuring vocabulary skill for 4 year old children. The scores on the test form a normal distribution with u = 70 and o = 20. A researcher would like to use the test to investigate the hypothesis that children who grow up as an only child develop vocabulary skills at a faster rate than children in larger families. A sample of n=25 only children is obtained and the mean test score for the sample is M = 77. Perform a two tailed hypothesis test, with an alpha level of .05, and add an APA summary.
