Question:
The claim is that the proportion of drowning deaths children attributable to beaches is more than 0.25, and the sample statistics include 696 drowning deaths of children with 30% of them attributable to beaches. include all steps
Use the Original Claim to Create a Null
Hypothesis Ho and an Alternative Hypothesis H
Step 1. Identify the claim to be tested and express it in symbolic form.
Step 2. Give the symbolic form that must be true when the original claim is false.
Step 3. Consider the two symbolic expressions obtained so far:
Alternative hypothesis H, is the one NOT containing equality, so H, uses the symbol < or > or 7,
Null hypothesis Ho is the symbolic expression that the parameter equals the fixed value being considered.
Step 4: Significance Level a
• Significance Level
The significance level a for a Hypothesis test is the probability value used as the cutoff for determining when the sample evidence constitutes significant evidence against the null hypothesis. By its nature, the significance level a is the probability of mistakenly rejecting the null hypothesis when it is true: Significance level a = P (rejecting Ho when Ho is true)
Identify the test statistic that is relevant to the test and determine its sampling distribution (such as normal, t, X7) (1 of 2) Step 5. Identify the test statistic that is relevant to the test and determine its sampling distribution (such as normal, t, yz). The table on the following slide lists parameters along with the corresponding sampling distribution
Find the Value of the Test Statistic, Then Find
Either the P-Value or the Critical Values(s)
Step 6. Find the value of the test statistic and the -value or critical value(s).
