**Question 15**Data was collected for a sample of organic snacks. The amount of sugar (in mg) in each snack is summarized in the histogram below.**Graph Description:**The histogram displays the frequency of sugar amounts (in mg) across different intervals for organic snacks. The x-axis represents the amount of sugar in mg, with intervals ranging from 160 to 174 mg. The y-axis represents the frequency of snacks, indicating how many snacks fall into each sugar interval.- 160-162 mg: Frequency of 3- 162-164 mg: Frequency of 6- 164-166 mg: Frequency of 10- 166-168 mg: Frequency of 12- 168-170 mg: Frequency of 8- 170-172 mg: Frequency of 4- 172-174 mg: Frequency of 3**Question:**What is the sample size for this data set?**Answer Input:**n = ________**Submit Button:**[Submit Question]

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? : Click the icon to view the data. What are the hypotheses for this test? Data Table O A.

A study was conducted to examine the impact of speaking in public on college students. A class of 15 statistics students participated in the study. At the beginning of a lecture the students recorded their systolic blood pressure. During the lecture the instructor called on each student to stand and answer questions about topics in the lecture. After speaking the students once again recorded their blood pressure. The resulting values are given below along with summary statistics. before 107 123 128 125 136 108 130 113 105 136 146 138 108 149 132 after 141 142 146 136 144 111 132 114 103 133 140 130 100 133 113 difference -34 -19 -18 -11 -8 -3 -2 -1 2 3 6 8 8 16 19 before after difference mean 125.6 127.9 -2.267 st dev 14.53 15.45 14.03 Does this information indicate that blood pressure increased because of speaking?

I have attached the question
INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Autism) if a researcher would like to determine if there is a significant difference between "Autistic," "Normal," and "Mentally Retarded"? The researcher took measurements of the serum concentration of an antigen in three groups of children (Autistic, Normal, and Mentally Retarded). Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on "Autism"? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the serum concentration of antigen between "Autistic," "Normal," and "Mentally Retarded"? 2. What is the computed Mean of "Mentally Retarded" on the given data for Autism? Round it off to two decimal places. 3. What is the computed Standard Deviation of the "Autistic" group on the given data for Autism? Round it off to two decimal places.
