Which of the following scenario is free of social desirability bias? o a psychologist counts how many digits a 70 years old man can remember parents report number of hours their children spend on social media a day o a researcher observes a married couple discuss their recent argument. o a doctor asks patients how many cigarettes they smoke in a week

A psychologist counts how many digits a 70 years old man can remember.

Step-by-step explanation:

The social desirability bias is the tendency of survey responders to answer in a way that it will make them look better to the eyes of the examiner.

a) A psychologist counts how many digits a 70 years old man can remember: in this case, the man cannot control the total amount of digits he can remember, therefore, this study is free of social desirability bias.

b)  Parents report number of hours their children spend on social media a day: In this case, parents can lie about the number of hours their kids spend on social media to make it look as they have a good style of parenting. Therefore, this study is not free of social desirability bias.

c)  A researcher observes a married couple discuss their recent argument: In the case that the couple knows they are being observed, we can expect them to behave differently than how they would behave if they weren't being observed (this is a bias observed in psychology), therefore this is not free of social desirability bias.

d) A doctor asks patients how many cigarettes they smoke in a week: again, people could lie and give a smaller number to look better to the eyes of the doctor, therefore this is not free of social desirability bias.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
