Do state laws that allow private citizens to carry concealedweapons result in a reduced crime rate? the author of a studycarried out is reported as saying "the strongest thing i could sayis that i don't see any strong evidence that they are reducingcrime."a. is this conclusion consistent with testing h0: concealed weapons lawsreduce crime versus ha: concealed weapons lawsdo not reduce crime or with testing h0: concealed weaponslaws do not reduce crime versus ha: concealed weapons lawsreduce crime? explain. b. does the stated conclusion indicate that the null hypothesis wasrejected or not rejected? explain.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
