Answer 1

claim: most adults would erase all of their personal information online if they could. a software firm survey of 581 randomly selected adults showed 59% of them would erase all of their personal information online if they could. find the value of the test statistic.

let us assume most means greater than 50%.

Test statistic = 4.34

Ho: P=0.5, H₁: P > 0.5

p=0.59, n=581

Hypothesis test for proportion vs hypothesized value
	Observed	Hypothesized
	0.59	0.5	p (as decimal)
	343/581	291/581	p (as fraction)
	342.79	290.5	X
	581	581	n
		0.0207	std. error
		4.3387	z
