**Fill in the Blank Activity**The ____________ is a value used in making a decision about the null hypothesis and is found by converting the sample statistic to a score with the assumption that the null hypothesis is true.The [Dropdown Menu] is a value used in making a decision about the null hypothesis and is found by converting the sample statistic to a score with the assumption that the null hypothesis is true.---**Explanation:**In this fill-in-the-blank activity, participants are tasked with identifying the correct statistical term that describes the provided scenario related to hypothesis testing. The activity includes an interactive element with a dropdown menu allowing for the selection of the appropriate term. This activity is designed to help learners understand the process of hypothesis testing, specifically focusing on how a sample statistic is converted into a test statistic under the null hypothesis assumption. By engaging with this exercise, participants will reinforce their knowledge of hypothesis testing concepts and terminologies.There are no graphs or diagrams in this image.

Question Help v A candy company says that the colors of its candies are 15% yellow, 14% red, 21% orange, 23% blue, 16% green and 11% brown. In a randomly selected bag of the candies, there were 28 yellow, 21 red, 10 orange, 10 blue, 5 green, 19 brown. Is this sample consistent with the company's advertised proportions? Test an appropriate hypothesis and state your conclusion. Complete parts a through g below. a) If the company's candies are packaged in the advertised proportions, how many of each color should have been expected in the bag of candies Red (Type integers or decimals rounded to two decimal places as needed.)

A poll found that 80% of American adults believed that there was a conspiracy in the death of President Kennedy. A later poll asked 1097 American adults if they believe there was a conspiracy in the assassination, and found that 834 believe there was a conspiracy.

State the null and alternate hypothesis. Will you use a left tail, right tail or 2 tailed test? Identify the sampling distribution to be used: standard normal, Student’s t or chi squared. Find the value of the test statistic. Find the P-Value. Based on your answers, shall we reject or accept the null hypothesis? Write the conclusion in the context of the problem.
2. The steps of hypothesis testing You intend to draw a random sample in order to test a hypothesis about an unknown population mean. You will use a hypothesis test. A description of each of the steps of a hypothesis test follows, but they may be specified in the incorrect order. Specify the correct order of the steps. Determine the null and alternative hypotheses. Select a level of significance. Make a decision about the unknown population. Select a sample and compute the z-score for the sample mean.
