Nadya [2.5K]

Answer:

Test statistic =1.30

Step-by-step explanation:

Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.

                                             Men                Women            Difference

Sample size n                        60                     120

Proportion p_1, p_2              0.45                   0.35                 0.10

60 120 180

0.45 0.35 0.383333333

27 42 69

p = 0.3833

Std error for proportion difference = \bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2})\\=0.3833(0.6167)(\frac{1}{60}+\frac{1}{120})\\=0.0769

Test statistic = \frac{p_1-p_2}{\bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2})  }

=1.3008

=1.30

Jordan invests 600 in his savings account the interest rate is $6 per year find the simple interest rate earned in 3 years. Then
aleksklad [387]
I believe you meant that the interest rate is 6%. Interest rates are given as percents.

To find the simple interest, we just multiply the principal amount by the rate and then by the number of years.

600 x 0.06 x 3 = 108

The total amount including interest will be 708.
