Solve It! You need to always show that conditions are met for any test or confidence interval and these questions are from a population that we do not know the population parameters, z tests cannot be performed.Please Do not use z tests on this question!!!Solve it without using z tests!! 2. It is believed that the mean number of dogs owned by dog-owning householdss= .29. Carry out anis 2.1 dogs. An SRS of 35 dog owners has x=2 andappropriate test to see if the mean number of dogs owned by dog-owninghouseholds is something other than 2.1 dogs. Use a 1% level of significance.

We can use a t-test to solve this problem since the population standard deviation is unknown. To…

An Internet provider is trying to gain advertising deals and claims that the mean time the competitors' customers spend online per day is less than 39 minutes. You are asked to test this claim. (a) How would you write the null and alternative hypotheses if you represent the Internet provider and want to support the claim? (b) How would you write the null and alternative hypotheses if you represent a competing advertiser and want to reject the claim? (a) Ho Ha 39 ▼39 Check answer
Paul correctly predicted the winner of 12 out of 14 games (for each game there was an equal chance that he would pick either of the two teams) You want to test the null hypothesis ``Paul was just guessing". You decide that you'll reject the null hypothesis and admit that Paul had a special gift if you calculate ? to be 0.01 or less. What is the p value?
Please show all work so I can understand!
after checking the hypothesis tests, please explain briefly how you should proceed given the result of recent hypothesis tests and what the owner should do

If we have a sample of size 100 from a population of rope with sample mean breaking strength of 960 pounds with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength is less than 1000 pounds, then what is the TYPE I ERROR? NONE OF THE OTHERS The population mean was actually less than 960 pounds, but our data leads us to conclude it is at least 960 pounds, The population mean breaking strength is at least 1000 pounds but our data leads us to conclude it is less than 1000 pounds. The population mean breaking strength is not equal to 1000 pounds, but our data leads us to us to conclude it is equal to 1000 pounds. The population mean breaking strength is actually less than 1000 pounds, but our data leads us to us to conclude it is at least 1000 pounds.
