Answer:
The sample data confirm the geneticist's prediction that 75% of the offspring from this cross will have red flowers.
Step-by-step explanation:
A Chi-square goodness of fit test can be used to test the claim made by the geneticist.
The hypothesis is defined as:
<em>H₀</em>: There is no difference between the observed and expected value,i.e. <em>p</em>₁ < 0.75.
<em>Hₐ</em>: There is a significant difference between the observed and expected value, i.e. <em>p</em>₁ > 0.75.
The test statistic is:
Consider the tables attached below.
The value of the test statistic is:
The critical value is:
*Use a Chi-square table.
The critical region is:
The test statistic value of 25.8133 lies in the critical region.
The null hypothesis is rejected at 1% level of significance.
<u>Conclusion</u>:
As the null hypothesis is rejected it can be concluded that 75% of the offspring from this cross will have red flowers.
Answer:
the image is drawn at a 1:2 scale to the origional
Answer:
The area of the deck after she doubles the length and width will be of 384 square feet.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of length l and width w is given by:
Doubling length and width:
If we double the length and the width, the dimensions are 2l and 2w. Thus, the area will be of:
That is, if both dimensions are doubled, the area is multiplied by 4.
What will the area of the deck be after she doubles the length and width?
Was 96. Then, both dimensions were doubled, and the area has to be multiplied by 4.
96*4 = 384
The area of the deck after she doubles the length and width will be of 384 square feet.
<h3><u>
Answer:</u></h3>
- The chance of getting a 5 or 6 in the next turn is about 40%.
<h3><u>Step-by-step explanation:</u></h3>
- => (5 + 3) ÷ (3 + 3 + 0 + 6 + 3 + 5)
- => 8 ÷ 20
- => 8/20
- => 4/10
- => 0.40
- => 0.40 x 100
- => 40%
<h3><u>Conclusion:</u></h3>
Therefore, the chance of getting a 5 or 6 in the next turn is about 40%.
