A teacher claims that fewer than 25% of his students are ready for class each day. -State the claim -State the opposite of the claim -State the null hypothesisd.State the alternative hypothesis -State the type of test (left tailed, right tailed, or two tailed) -Use α = 0.05 to find the critical z-value used to test the null hypothesis

Angel believes a coin is “fair,” the other believes the coin is biased toward heads. The coin is tossed 20 times, yielding 15 heads. Indicate whether or not the first researcher’s position is supported by the results. Use α = .05. Express statistically the null and alternative hypotheses.

Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%

EXAMPLE Formulating Hypothesis Statements 1. Do female students' study, on average, more than male students do? Null Hypothesis (H): On average, women do not study more than men do. Alternative Hypothesis (H,): On average, women do study more than men do. 2. Are Side Effects Experienced by Fewer than 205 of 3. The average TV viewing time of all five – year old children in the province is more than 4 hours daily. Patients? Pharmaceutical company wants to claim that the proportion of patients who experience side effects is less Null Hypothesis (H,): The average viewing time of all five- year old children in the province is equal to 4 hours daily. than 20%. (The claim that the company hopes to prove is used as the alternative hypothesis.) In Symbol: Hp: µ = 4 Null Hypothesis (H,): 20% (or more) of users will experience side effects. Alternative Hypothesis (H.): The average viewing time In Symbol: Ho: p 20%; Alternative Hypothesis (H.): Fewer than 20% of of all five- year old children in…

When we test the hypothesis, can you explain the difference between one and of two-sample tests? How would I know if I can reject this null hypothesis? Can you give an example of the one and two-sample tests? Why does the t-value have different formulas in a two-sample test?

A risky eye surgery for patients in danger of permanent blindness is known to historically cure the condition in 35% of all cases of performing the surgical procedure. A new procedure is proposed for which the researchers claim that they will improve that rate of cure.  -Write an appropriate null and alternate hypothesis for the researchers to test their claim.

Can you please help me located the null?

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a=0.05, and (c) a= 0.10. P=0.0596 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA Fail to reject Hg because the P-value, 0.0596, is greater than a= 0.01. OB. Reject Ho because the P-value, 0.0596, is greater than a= 0.01. OC. Fail to reject Hg because the P-value, 0.0596, is less than a=0.01. %3D OD. Reject Ho because the P-value, 0.0596, is less than a= 0.01. %3D
