From 1995 - 2008 in the US 648 people were struck by lightening. 531 of them were men. You want to see if this observation differs from the null hypothesis, that 50% of people who are hit by lightening would be men, based on the proportion of men in the population as a whole. Calculate the probability under the normal distribution of getting a result of 531 or more (including the continuity correction). Use the binomial test with a normal approximation. What is your conclusion?

Answers

Answer 1

Answer:

Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis

Step-by-step explanation:

Sample proportion = p= 531/648 = 0.8194

This is the proportion of men that were hit by lightening

Null hypothesis: H0: p = 0.5

Alternate hypothesis: H1: p ≠ 0.5

Test statistics z = 0.8194-0.5/(√0.5x0.5/648)

= 0.8194-0.5/√0.0003858

= 0.3194/0.019642

= 16.26

Since the z > 1.96 (at 5% significance) we reject the null hypothesis.

Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

If you deposit $850 into an account which earns 6% yearly interest compounded monthly, how much will be in the account after 4 years, assuming you never withdraw money from the account? Round your answer to the nearest cent if necessary and do not include the dollar sign.

Answers

Answer:

1079.9

Step-by-step explanation:

A = P(1 + [tex]\frac{r}{n}[/tex])^nt

A: ending amount

P: principal (850)

r: interest rate in decimal form (.06)

n: compounding periods, 12 months in a year.

t: time in years (4)

   = 850(1 + .06/12)^12(4)

    = 850(1.005)⁴⁸

  1. 1/(3+1+2) = 1/6

  2. 2/(5+2+3) = 2/10 = 1/5

Write in slope intercept form:
(-5,-11) and (-2,1)

Answers

Answer:

y = 4x + 9

Step-by-step explanation:

First, find the slope of the line, which is the change in y/the change in x:

(-11-1)/(-5-(-2)) = -12/-3 = 4

That leaves you with the equation:

y = 4x

But notice, when x = -2 in the equation, y = -8, but we want it to be 1, so we add 9 to the end of the equation:

y = 4x + 9

Two part-time instructors are hired by the Department of Statistics and each is assigned at random to teach a single course in probability, inference, or statistical computing. Assume that more than one section of each course is offered. List the outcomes in the sample space [Hint: each element consists of a pair of assignments]. Find the probability that they will teach different courses. Note: carefully define your notation (e.g. any events) in words before solving the problem.

Answers

Answer:

The probability that they will teach different courses is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:

Sample space is a set of all possible outcomes of an experiment.

In this case we will write the sample space in the form (x, y).

Here x represents the course taught by the first part-time instructor and y represents the course taught by the second part-time instructor.

Denote every course by their first letter.

The sample space is as follows:

S = {(P, P), (P, I), (P, S), (I, P), (I, I), (I, S), (S, P), (S, I) and (S, S)}

The outcomes where the the instructors will teach different courses are:

s = {(P, I), (P, S), (I, P),(I, S), (S, P) and (S, I)}

The probability of an events E is the ratio of the number of favorable outcomes to the total number of outcomes.

[tex]P(E)=\frac{n(E)}{N}[/tex]

Compute the probability that they will teach different courses as follows:

[tex]P(\text{Different courses})=\frac{n(s)}{n(S)}=\frac{6}{9}=\frac{2}{3}[/tex]

Thus, the probability that they will teach different courses is [tex]\frac{2}{3}[/tex].

At its height in the late 18th century, New Spain stretched south from present-day western Canada through North America, west of the Mississippi and including the Caribbean, to the northern tip of South America.

New Spain: the Spanish colonies of the Western Hemisphere north of present-day South America administered: managed or run by pertained: had to do with social reality: the actual relationship between groups of people; what people's day-to-day lives were like in terms of relationships Spain maintained control of its colonies by imposing two legal systems: one that pertained to Europeans (the repblica de espaoles) and one for native peoples (the repblica de indios). In practice, racial mixing produced a much more complicated social reality. As a result, social status in colonial Mexico was the result of a caste system based on differences in wealth, inherited rank, culture, and skin color. European-born Spaniards received the greatest social privileges and legal protections. The next tier included Criollos, also known as Creoles (Mexican-born people of Spanish descent who were considered white).
