It is commonly held that around 15.7% of American college students regularly use marijuana. A certain school wants to determine if its percentage is higher than the national average. They take a random sample of 100 students and want to use those data to test a hypothesis. What conditions, if any, are not met to be able to run a hypothesis test? O Sample Size Condition O 10% Condition O Randomization Condition O None of these; all conditions for a hypothesis test are met

How much is in the can? A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Following are the amounts measured in a simple random sample of eight cans.                   11.96 12.10 12.04 12.13 11.98 12.05 11.91 12.03 Following is a dotplot for these data. Is it reasonable to assume that the conditions for performing a hypothesis test are satisfied? Explain (diagrem. jpg goes here) 2. If appropriate, perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the ɑ = 0.05 level of significance. What do you conclude?

A high p-value, such as 0.8, provides evidence to say the null hypothesis is true. This statement is true. O This statement is false.

a statistics instructor belives that fewer than 25% of NRCC students have a cable TV subcription and instead prefer streaming content. What is the correct NULL hypothesis for this scenario? a. p< .25 b. p< or equal to .25 c. p >.25 d. p > or equal to .25

When asked what it means for the result of a hypothesis test to be practically significant (or practically important), Tatum says this means that the P-value is small and the null hypothesis has been rejected.  Why is Tatum wrong?

High School Band - In most US high schools, students can play an instrument in three types of bands. A random sample of high school band students was taken and the results are summarized in the table below. Instrument type Band Woodwind Brass Percussion type Concert 31 25 8. Jazz 10 16 10 Marching 65 65 27 To assess whether there is a relationship between band type and instrument type, we want to conduct an appropriate hypothesis test. Choose the null and alternative hypothesis? 1. The categorical variables band type and instrument type are independent. Alternative hypothesis 2. The categorical variables band type and instrument type are not independent. Null hypothesis

In hypothesis testing, if the test statistic is negative, this means the sample statistic is larger than the claimed population parameter. O we call the initial claim being tested about the population an alternative hypothesis. the "P" in P-value stands for "personal." O it is necessary to know the population size in order to compute the test statistic. O results that are statistically significant may or may not be practically important (or practically significant).

Is the following a null or an alternative hypothesis? Iced coffee tastes better than hot coffee.
