**Educational Website Text:**A scientist has read that the mean birth weight of babies born at full term is 7.4 pounds. The scientist has good reason to believe that the mean birth weight of babies born at full term, denoted as μ, is different from this value and plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.8 pounds and the standard deviation to be 1.8 pounds.Based on this information, complete the parts below:**(a) What are the null hypothesis \( H_0 \) and the alternative hypothesis \( H_1 \) that should be used for the test?**- \( H_0: \) [ ]- \( H_1: \) [ ]**(b) Suppose that the scientist decides not to reject the null hypothesis. What sort of error might she be making?**- [Choose one]**(c) Suppose the true mean birth weight of babies born at full term is 7.4 pounds. Fill in the blanks to describe a Type I error:**"A Type I error would be (Choose one) the hypothesis that \( μ \) is (Choose one) (Choose one) when, in fact, \( μ \) is (Choose one)."**Explanation of Diagrams:**There are no graphs or diagrams present in the image. The image contains text fields and multiple-choice options which are meant to guide the learner through filling in hypotheses and understanding statistical errors.

The type I error is defined as the rejecting the null hypothesis when actually it is true. The type…

Español Try Again Your answer is incorrect. The proportion of residents in a community who recycle has traditionally been 65%. A policy maker claims that the proportion is less than 65 % now that one of the recycling centers has been relocated, and the policy maker wishses to carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that the policy maker would use for this test. Ho: 0.65 Aa H: 0.65 S O

Q1A Hi wonderful Bartleby team, I need help with this exercise, please provide answer and short explanation for all the answers. Thanks in advance. The last part of it is the sentence and the options are: -(Reject/ Fail to reject) the null hypothesis. There (Is / Not) sufficient evidence to support the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment.

A researcher wanted to determine if carpeted rooms contain more bacteria than uncarpeted rooms. The table shows the results for the number of bacteria per cubic foot for both types of rooms. Full data set O Carpeted Uncarpeted 9.4 9.1 16 10.8 6.4 10.8 14.8 8.8 11.5 11.6 13.7 9.4 10.7 12.4 13.4 7.8 Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.05 level of significance. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. State the null and alternative hypotheses.
