Answer:

This is a __simple____ hypothesis and will result in a(n) _______one-tailed test.

Step-by-step explanation:

The Simple Hypothesis predicts the relationship between two variables, in this case, height and leadership. The one-tailed test will be performed to determine whether to reject the null hypothesis.  This is why the null and alternative hypotheses must be established before the statistic test is carried out.   If the null hypothesis is rejected, this simply results in the acceptance of the alternative hypothesis.

koban [17]

Answer:

Step-by-step explanation:

The total number of magnets that Lisa and Bill made for the craft fair is 60.

They sold about 55% of the magnets. The number of magnets that they sold would be about

55/100 × 60 = 0.55 × 60 = 33

If Lisa says that they sold about 30 magnets, she is correct because if we round off 33 to the nearest ten, it would be 30 magnets.

If Bill says that they sold about 36 magnets, he is wrong because if we round off 36 to the nearest ten, it would be 40 magnets.

A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a fu
den301095 [7]

Answer:

y =120*1.1^x

r = 10\% --- Percentage increase

Step-by-step explanation:

Given

Let

x \to months

y \to mice

So, we have:

(x_1,y_1) = (0,120) --- Monday

(x_2,y_2) = (1,132) --- One month later

Required

The function

The function is represented as:

y = ab^x

In (x_1,y_1) = (0,120), we have:

120 =a * 1

120 =a

Rewrite as:

a = 120

In (x_2,y_2) = (1,132), we have:

132 = a * b^1

132 = a * b

Substitute a = 120

132 = 120 * b

Solve for b

b = \frac{132}{120}

b = 1.1

Recall that:

y = ab^x

Hence, the function is:

y =120*1.1^x

To get the monthly percentage increase (r), we have:

y = a(1 + r)^x

Compare to: y = ab^x

So:

1+r =b

Make r the subject

r = b-1

r = 1.1-1

r = 0.1

Express as percentage

r = 0.1*100\%

r = 10\%
