a.
To explain: The way of accounting the design of the provided experiment for the placebo effect.
a.
Explanation of Solution
Given:
It has been stated that placebo is more effective than the herb.
If the patients are provided with the pill that exactly taste and look like the Saint John’s wort but it does not have any effect. It would make patient to think that they are being treated but actually they are not. If that pills improve their condition it would be considered as the placebo effect.
b.
To explain: The reason of double-blind design being a good method in the provided study.
b.
Explanation of Solution
Here, both the researcher and subjects must not be known about the treatment that the subjects are getting. Here, researchers should also be blinded so they are unable to check out the influence.

Ella is a 9-year-old third-grade student in an inclusive classroom. She has been diagnosed with Emotional and Behavioural Disorder (EBD). She has been struggling academically and socially due to challenges related to self-regulation, impulsivity, and emotional outbursts. Ella's behaviour includes frequent tantrums, defiance toward authority figures, and difficulty forming positive relationships with peers. Despite her challenges, Ella shows an interest in art and creative activities and demonstrates strong verbal skills when calm. Describe 2 strategies that could be implemented that could help Ella regulate her emotions in class (4 marks) Explain 2 strategies that could improve Ella’s social skills (4 marks) Identify 2 accommodations that could be implemented to support Ella academic progress and provide a rationale for your recommendation.(6 marks) Provide a detailed explanation of 2 ways…arrow_forward
- Question 2: When John started his first job, his first end-of-year salary was $82,500. In the following years, he received salary raises as shown in the following table. Fill the Table: Fill the following table showing his end-of-year salary for each year. I have already provided the end-of-year salaries for the first three years. Calculate the end-of-year salaries for the remaining years using Excel. (If you Excel answer for the top 3 cells is not the same as the one in the following table, your formula / approach is incorrect) (2 points) Geometric Mean of Salary Raises: Calculate the geometric mean of the salary raises using the percentage figures provided in the second column named “% Raise”. (The geometric mean for this calculation should be nearly identical to the arithmetic mean. If your answer deviates significantly from the mean, it's likely incorrect. 2 points) Starting salary % Raise Raise Salary after raise 75000 10% 7500 82500 82500 4% 3300…arrow_forwardI need help with this problem and an explanation of the solution for the image described below.
