Eleven different video games showing drug use were observed. The duration times of drug use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 7'9 sec, what does df denote, and what is its value? H What does df denote? The sample size The test statistic The sample standard deviation V The number of degrees of freedom The value of df is . (Type an integer or a decimal. Do not round.) The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.6?0 g as required by mint specications. The sample size is n = 36 and the test statistic is t = - 3.018. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10. State the null and alternative hypotheses. H0:u V H1:u V (Type integers or decimals. Do not round.) A data set includes weights (in grams) of 32 Reese's Peanut Butter Cup Miniatures. The accompanying Statdisk display shows results from using all 32 weights to test the claim that the sample is from a population with a mean equal to 8.953 g. Test the given claim by using the display provided from Statdisk. Use a 0.05 significance level. 0 Click the icon to view the Statdisk display. Identify the null and alternative hypotheses.
