mr. dean has an even number of cats and an odd number of dogs. which of these choices could tell about his pets ? 6 cats and 3 d

valina [46]

Even numbers can be divided evenly into groups of two. The number four can be divided into two groups of two.

Odd numbers can NOT be divided evenly into groups of two. The number five can be divided into two groups of two and one group of one.

Even numbers always end with a digit of 0, 2, 4, 6 or 8.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 are even numbers.

Odd numbers always end with a digit of 1, 3, 5, 7, or 9.
1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31 are odd numbers.

The correct answer is 6 cats and 3 dogs.

It is known that a particular laboratory task takes the average person 2.5 seconds. A researcher was interested in whether older

Alchen [17]

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that older people are slower

Step-by-step explanation:

From the question we are told that

The average time taken is $\mu = 2.5 \ seconds$

The sample size is $n = 30$

The sample mean is $\= x = 2.7 \ seconds$

The standard deviation is $\sigma = 1.4 \ seconds$

The null hypothesis is $H_o: \mu = 2.5$

The alternative hypothesis is $H_a : \mu > 2.5 \ seconds$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{\sigma }{ \sqrt{n} } }$

=> $z = \frac{ 2.7 -2.5 }{ \frac{1.4}{ \sqrt{30} } }$

=> $z = 0.7825$

From the z table the area under the normal curve to the right corresponding to 0.7825 is

$p-value = P(Z > 0.7825 ) = 0.21696$

So from the question we see that the $p-value > \alpha$ hence

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that older people are slower
