What is the critical Z Value?What is the decision making for this hypothesis test? A is the positive critical value for this question, what is/are the possible critical region(s) for this hypothesis test? This image displays a symmetrical bell-shaped curve, commonly known as a Gaussian or normal distribution curve. - **Horizontal Axis**: The central point of the curve is marked as 0, representing the mean of the distribution. To the left, the axis is labeled `-A`, and to the right, it is labeled `A`. These points could represent standard deviations away from the mean in a typical normal distribution.- **Vertical Axis**: Although not labeled, this axis signifies the probability density or frequency of occurrence for values along the horizontal axis.- **Curve Characteristics**: The highest point of the curve indicates the mean, median, and mode, all of which coincide in a normal distribution. The curve tails off symmetrically towards both ends, approaching but never touching the horizontal axis. This graph is often used in statistics to represent data that tends to cluster around a mean. It is essential for understanding concepts such as standard deviation and statistical variance.

We want to find the critical value and rejection region at alpha=0.05

Ex: 0.123 Does sufficient evidence exist to support the claim that the level of support in city 1 is lower than that of city 2 at the α=0.1 significance level? Ex: yes or no
There are 3 parts to this question The value of the standard score is (round to two decimal places as needed) The critical value(s) is/are (use a comma to separate the answers as needed. Round to two decimal places as needed.) Determine whether the alternative hypothesis is supported at a 0.01 significance level.
How to use two-tailed hypothesis tests using the critical value approach at the 5% significance level?
Hypothesis Test Requirements For all questions involving a hypothesis test, be sure to include all the required steps: 1. State the null (Ho) and alternative (H or HA) hypotheses and identify the claim. 2. Using the sample data, compute the test statistic. 3. Using the level of significance, calculate the critical value. 4. Compute the p-value. 5. Using the test statistic and critical, make a decision: Reject Ho or Fail to reject Ho. Using the p-value and level of significance, make a decision: Reject Ho or Fail to reject Ho. 6. Interpret the results in the context of the original problem. Decision: Reject Ho Decision: Fail to reject Ho Claim: "There is sufficient evidence to warrant rejection of the claim that (original claim)." "There is not sufficient evidence to warrant rejection of the claim that .... (original claim). Ho www Claim: "The sample data support the claim that ... (original claim)." "There is not sufficient sample evidence to support the claim that (original claim). Ha
