The dog food company claims that the mean weight of a bag of food is 30 pounds. A sample of 36 bags of food found the sample mean to be 29.6 pounds with a standard deviation of 0.5 pounds. We want to test if the dog food bags actually weigh less than 30 pounds. Conduct a hypothesis test at the 0.05 significance level. (a) State the null and alternative hypothesis on your scratch paper. (b) Using your calculator find the test statistic. Round to 1 decimal places. (c) State the p-value. enter exactly what your calc outputs. (d) Do you reject the null hypothesis or fail to reject the null hypothesis? Why? State on your scratch paper. (e) Interpret your decision. State on your scratch paper.

ScLi6- Identify reseаrch questiоns/gаps аddressed by research papers A hypоthetical study оn autism is stating that: Despite extensive research on autism spectrum disorder (ASD), there remains a significant gap in our understanding of the early developmental markers that can predict the onset of autism. While behavioral symptoms of autism typically become apparent by the age of three, the subtle early indicators during infancy and their biological underpinnings are not well understood. Identifying these early markers is crucial for timely diagnosis and intervention, which can significantly improve outcomes for children with autism. Current studies have focused largely on observable behaviors in later stages, leaving a gap in the early detection and understanding of the neurobiological changes that precede these behaviors. Which would be the most likely research question addressed in this study?
