Can someone help me with these three questions?

Mathematics
1 answer:
N76 [4]2 years ago
5 0

Answer:

1. =

2. <

3. <

Step-by-step explanation:

Note: When comparing decimals you always place both decimals right above each other.

1 is equal to because once you put a 0 behind the 2.1 they are both the same.

2.10

2.1    <add 0 as space holder

2 is less than because they are both negative you are looking for which one is closest to zero.

-4.5   <add 0 as place holder

-4.25   <closest to zero

3 is less than because \pi(pie) equals 3.141592654 which is less than 3.2.

3.141   <do not need to add whole decimal

3.2   <add two 0's as a placeholder

Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit
SCORPION-xisa [38]

Answer:

Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.

Step-by-step explanation:

We are given the following hypothesis below;

Let p = <u><em>proportion of people who write with their left hand</em></u>

So, Null Hypothesis, H_0 : p = 0.22     {means that the proportion of people who write with their left hand is equal to 0.22}

Alternate Hypothesis, H_A : p \neq 0.22      {means that the proportion of people who write with their left hand is different from 0.22}

Now, Type I error states that we conclude that the null hypothesis is rejected when in fact the null hypothesis was actually true. Or in other words, it is the probability of rejecting a true hypothesis.

So, in our question; Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error states that we conclude that the null hypothesis is accepted when in fact the null hypothesis was actually false. Or in other words, it is the probability of accepting a false hypothesis.

So, in our question; Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.
