Why is it important to be aware of marketing tricks?

ddd [48]

Because people in the market can use it against you / scam you.
If you know someone doesn't have any prior knowledge of what you're selling you can easily say," this helped my grandma cure her cancer" etc. You could easily be used if you're not aware.

11. An experiment is set up to study the weights of 45 frogs after they are given a hormone treatment. The population mean is 22

sveta [45]

Answer: The standard error of the sample mean = 0.44

Step-by-step explanation:

Standard error of the sample mean = $\dfrac{\sigma}{\sqrt{n}}$ <em> , where </em> $\sigma$ = population standard deviation , n= sample size.

Given : n= 45 , $\sigma= 2.96$ grams

The e standard error of the sample mean $=\dfrac{2.96}{\sqrt{45}}$

$=\dfrac{2.96}{6.7082039325}\\\\\approx\ 0.44$

Hence, the standard error of the sample mean = 0.44
