A software firm survey of 595 randomly selected adults showed that 38​% of them would erase all of their personal information on
algol [13]

Answer:

a. \ p=0.38\\\\b. \ \ H_o:p=0.38\\\ \ \ \ \\H_A:p\neq 0.38

Step-by-step explanation:

a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.

-we know that the value of probabilities are in the range [0,1]:

-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5

b. The null hypothesis usually represents the true value parameter under study.

-As stated above, the true value of the parameter is 38%;

-Hence, the null hypothesis is H_o:p=0.38

#Alternative hypothesis is the control value, given the value of the parameter  p=0.38, the alternative hypothesis is that p has a different value other than 0.39:

H_A:p\neq 0.38

Serggg [28]

Use the definition of conditional probability:

P(\text{sports}\mid\text{senior})=\dfrac{P(\text{sports AND senior})}{P(\text{senior})}

We know that 0.10 of students belong to both categories, and that 0.25 of students are seniors, so

P(\text{sports}\mid\text{senior})=\dfrac{0.10}{0.25}=0.40

grigory [225]
There are 2000 pounds in one ton, so to find the amount of pounds in a set amount of tons, all we need to do is multiply the amount of tons by the amount of pounds in one ton.

12 * 2000 = 24000

There are 24,000 lbs in 12 tons.
