Researchers examined the bill color (in hue degree) of male and female zebra finches. Here are the summary statistics from the s

sesenic [268]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In the question some iformation is missing, which can be defined as follows:

Given:

The value of males:

$n_1= 59\\s_1= 1.46\\\bar y_1=2.91\\$

The value of Females:

$n_2=60\\s_2= 2.48\\\bar y_2=7.42\\$

Calculating Degrees of Freedom:

$\bold{ df=\frac{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}{ \frac{1}{n_1-1} (\frac{s_1^2}{n_1})^2+\frac{1}{n_2-1} (\frac{s_2^2}{n_2})^2}}\\\\\\$

$=\frac{(\frac{1.46^2}{59}+\frac{2,48^2}{60})^2}{ \frac{1}{59-1} (\frac{1.46^2}{59})^2+\frac{1}{60-1} (\frac{2.48^2}{60})^2}\\$

$=9.58 or 95$

$\alpha= 1-0.95\\\\$

$= 0.05$

for 95% confidence interval are:

$\frac{\alpha}{2} = \frac{0.05}{2} = 0.025$

From its t-distribution table , the value of t has an region of ( $\frac{\alpha}{2} \ \ 0.025$ ) for (df=95) in its upper tail.

shall be given by = t {0.025}=1.985

Calculating the margin of Error:

$M_OE =t_{0.025} \times \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$=1.985\times \sqrt{\frac{1.46^2}{59}+\frac{2.48^2}{60}}\\\\=0.739$

The difference in mean bill color " $\mu_2 -\mu_1$ " with 95% confidence intervals:

$\to (7.42 - 2.91) \pm 0.739\\\\\to 4.51 \pm 0.739$

Lower limit=3.771

Upper limit = 5.249

Yakvenalex [24]

Answer:

30% that he chooses red and 30% that he chooses blue.

Step-by-step explanation:

4+3+3=10

Probabilities that he chooses green = 4/10 = 40%

Red = 3/10 = 30%

Blue = 3/10 = 30%

The maximum point on the graph of the equation

joja [24]

Answer:

(6, - 3 )

Step-by-step explanation:

Given f(x) then f( x + c) represents a horizontal translation of f(x)

• If c > 0 then a shift to the left of c units

• If c < 0 then a shift to the right of c units, thus

y = f(x - 4) represents a shift to the right of 4 units, so

(2, - 3 ) → (2 + 4, - 3 ) → (6, - 3 )

Hunter has a quarters and y dimes, having at least 18 coins worth at most

garik1379 [7]

Answer:The number of nickles is 6

The number of dims is 12 .

Step-by-step explanation:

Given as :

Sum of total number of dims and nickels coins = 18

The value of total combination = $1.50

Let The total number of dims = d

Let The total number of nickels = n

1 nickles = $0.05

1 dims = $0.1

According to question

Total number of dims and nickels coins = number of dims + number of nickels

Or, d + n = 18 .........1

And

$0.1 ×d + $0.05 ×n = $1.50

Or, 0.1 d + 0.05 n = 1.50 .........2

Now, Solving eq 1 an eq 2

0.1 × (d + n) - (0.1 d + 0.05 n) = 0.1 × 18 - 1.50

Or, (0.1 d - 0.1 d) + (0.1 n - 0.05 n) = 1.8 - 1.50

Or, 0 + 0.05 n = 0.3

Or, 0.05 n = 0.3

∴ n =

i.e n = 6

So, The number of nickles = n = 6

Put the value of n int eq 1

∵ d + n = 18

Or, d = 18 - n

Or, d = 18 - 6

i.e d = 12

So, The number of dims = d = 12

Hence, The number of nickles is 6 and the number of dims is 12 .
