Educators are testing a new program designed to help children improve their reading skills. The null hypothesis of the test is t

hat the program does not help children improve their reading skills. For the educators, the more consequential error would be that the program does not help children improve their reading skills but the test indicated that it does help.
Which of the following should the researchers do to avoid the more consequential error?

a. Increase the significance level to increase the probability of Type I error.
b. Increase the significance level to decrease the probability of Type I error.
c. Decrease the significance level to increase the probability of Type I error.
d. Decrease the significance level to decrease the probability of Type I error.
e. Decrease the significance level to decrease the standard error.

The cable company is analyzing data from two satellite television providers to determine whether their users spend more time wat
Phoenix [80]

Answer:

59%

Step-by-step explanation:

The information from Satellite Company Y is:

65 people watch live and 94 people watch recorded.

The total number of people from Y is:

65 + 94 = 159

So the probability that a random person from Y watches recorded shows more often is given by the division of the number of people watching more recorded shows (94) over the total number of people (159):

Probability = 94 / 159 = 0.5912 = 59.12%

Rounding to nearest whole percent, we have 59%

Solve the equation by clearing the decimals: 0.8x -0.3 = 0.7x + 0.2
Mashutka [201]

Answer:

x = 5

Step-by-step explanation:

0.8x - 0.3 - 0.7x = 0.2

0.8x - 0.7x = 0.2 + 0.3

0.1x = 0.2 + 0.3

0.1x = 0.5

Find the greatest common divisor of 100 and 254, using • prime factorization- • euclidean algorithm-
larisa [96]
Via prime factorization:

100=10^2=2^2\cdot5^2
254=2\cdot127

of which the only common factor is a single power of 2, so \mathrm{gcd}(100,254)=2.

Via the Euclidean algorithm:

254=2\cdot100+54
100=1\cdot54+46
54=1\cdot46+8
46=5\cdot8+6
8=1\cdot6+2
6=3\cdot2+0

which means \mathrm{gcd}(100,254)=2, as expected.
