A random sample of 160 commercial customers  revealed that 32  had paid their accounts within a month of billing. Can normality be assumed for the sample proportion?

What is the P(t >  -1.8) with a sample size of 10.

a population proportion of 0.61. Suppose a random sample of 662 items is sampled randomly from this population

Select the correct answer below:   p-value>0.10   0.05< p-value <0.10   0.01< p-value <0.05   p-value <0.01

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 0.46. Your sample data produce the test statistic z=1.883. Find the p-value accurate to 4 decimal places.

Bruce was reading an article.  In the Methods section it said that a within subjects ANOVA was carried out.  In the Results section, he saw that an SPSS phrase, F (8, 192) = 23.00, p < 0.05.  How many levels of the factor did the study have?\

On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.

A student conducted a test at 0.05, and she found the 95% CI to be [4.79,7.25]. The mean for the sample is 6.12. Is the conclusion for the test that there is a significant difference or that there is not a significant difference?  You should fully explain how you can use this information to draw a conclusion.

The best way to ensure that your sample represents the population it came from accurately, is to make sure you have a sample of at least 10. (n=10) True or false
