The times it took for 35 loggerhead sea turtle eggs to hatch in a simple random sample are normally distributed, with a mean of

50 days and a standard deviation of 2 days. assuming a 95% confidence level (95% confidence level = z-score of 1.96), what is the margin of error for the population mean? remember, the margin of error, me, can be determined using the formula . 0.06 0.11 0.34 0.66

<u>Answer-</u>

<em>The margin of error is </em><em>0.66</em>

<u>Solution-</u>

The times it took for 35 loggerhead sea turtle eggs to hatch in a simple random sample are normally distributed, with a mean of 50 days and a standard deviation of 2 days.

So here,

sample size = n = 35

confidence level (95%) = z = 1.96

mean = μ = 50

standard deviation = s = 2

We know that,

ME=\dfrac{z\cdot s}{\sqrt{n}}

Putting the values,

ME=\dfrac{1.96\times 2}{\sqrt{35}}=0.66

Therefore, the margin of error is 0.66

We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)

The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%

Which representation of a transformation on a coordinate grid does not preserve congruence?
Alex17521 [72]

Answer:

B

Step-by-step explanation:

Consider all options:

A. Transformation with the rule

(x,y)\rightarrow (x,-y)

is a reflection across the x-axis.

Reflection across the x-axis preserves the congruence.

B. Transformation with the rule

(x,y)\rightarrow \left(\dfrac{7}{8}x,\dfrac{7}{8}y\right)

is a dilation with a scale factor of \frac{7}{8} over the origin.

Dilation does not preserve the congruence as you get smaller figure.

C. Transformation with the rule

(x,y)\rightarrow (x+6,y-4)

is a translation 6 units to the right and 4 units down.

Translation 6 units to the right and 4 units down preserves the congruence.

D. Transformation with the rule

(x,y)\rightarrow (y,-x)

is a clockwise rotation by 90^{\circ} angle over the origin.

Clockwise rotation by 90^{\circ} angle over the origin preserves the congruence.
