A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed​ populations, and do not assume that the population standard deviations are equal. Complete parts​ (a) and​ (b) below. Use a 0.10 significance level for both parts.

Certainly, I can help with that. To proceed, I'll need the specific data from the table for the treatment and placebo groups. Typically, such a table would include the sample sizes, means, and standard deviations for both groups. Please provide this data so I can complete the analysis for parts (a) and (b).

If you have an image of the table, you can upload it, and I'll extract the necessary information.

After you provide the data, I'll:

1. Conduct a hypothesis test to compare the means of the two groups.
2. Calculate the confidence interval for the difference between the two means.

I'll explain each step in detail and ensure you understand the process.

Feel free to upload the table or provide the details in text format.
