Anchara drops a penny from a height of 60 feet above the ground. The equation h=-16t^2 + 60 models the penbys height h i feet as

weeeeeb [17]

Answer:

t = 1.94 seconds

Step-by-step explanation:

we have to solve the following polynomial equation:

-16t² + 60 = 0

16t² = 60

t² = 60/16 = 3.75

t = √3.75 = 1.936491673 seconds

the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option

Political parties rely heavily upon polling to measure their support in the electorate. In a country with four major political p

liberstina [14]

Answer:

a) The claim is not plausible

b) claim is plausible and the type of bias here is response bias

Step-by-step explanation:

Given data:

Number of political parties = 4

coffee party got the support of 435 out of 1183 randomly selected voters in a poll conducted.

A) Construct and interpret a 98% confidence interval to estimate the proportion of voters who support the coffee party

H0 ( null hypothesis ) : p = 0.42

Ha ( alternate hypothesis ) : p ≠ 0.42

z value for 98% confidence interval = 2.326

using 98% confidence interval the value of p = ( 0.3668, 0.3686 )

hence the claim is not plausible

B) Determine the type of bias

Assume the actual number of people = 1200

and 17 people did not respond

hence number of people who responded = 1200 - 17 = 1183

Therefore the claim by the manager is plausible because 17 people did not respond and the type of bias here is response bias

attached below is a detailed solution of the problem of the A part
