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:

$H_A:p\neq 0.38$

Point T is on line segment S U ‾ SU . Given S T = 6 ST=6 and T U = 10 , TU=10, determine the length S U ‾ . SU

Naily [24]

If Point T is on the line segment S U, then ST + TU = SU, Hence the length of SU is 16.

<h3>What is addition?</h3>

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

If Point T is on the line segment S U, then ST + TU = SU

Given;

S T = 6 and T U = 10

Substitute

SU = ST + TU

SU = 6 + 10

SU = 16

Hence the length of SU is 16.
