Claim: Most adults would erase all of their personal information online if they could.A software firm survey of 453 randomly sel

Anit [1.1K]

Answer:

The value of the test statistic is 4.26.

Step-by-step explanation:

In this case a hypothesis test is performed to determine whether most adults would erase all of their personal information online if they could.

A random sample of n = 453 adults were selected and it was found that 60% of them would erase all of their personal information online if they could.

Assume that the population proportion is, p = 0.50.

A z-test for single proportion would to used to perform the test.

Compute the value of the test statistic as follows:

$z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}$

$=\frac{0.60-0.50}{\sqrt{\frac{0.50(1-0.50)}{453}}}\\\\=\frac{0.10}{0.0235}\\\\=4.25532\\\\\approx 4.26$

Thus, the value of the test statistic is 4.26.

How do u divide fractions (the way you were taught)?

Aleks [24]

When given two fractions for example 2/3 divided by 3/6
the division sign changes to a multiplication sign and the fraction on the right swaps the numerator and the denominator so 3/6 becomes 6/3

so it will then be 2/3 x 6/3 and you get your answer
thats how you divide fractions
