It is desired to estimate the average weight of a new born baby. The birth records of arandom sample of 60 babies' weights showed a mean of 7.0 lbs and standard deviation of 1.5 lbs.Construct a 95% confidence interval forμ.

Answers

Answer 1

Answer:

Answer:

95% confidence interval for the mean

(6.61251, 7.38749)

Step-by-step explanation:

Step:-1

Given that a random sample 'n' = 60

Given that mean of the sample x⁻ = 7.0

Given that the standard deviation of the sample (S) = 1.5

Level of significance = 0.05

Degrees of freedom = n-1 = 60-1 = 59

t₍₀.₀₅ , ₙ₋₁₎ = 2.0010

Step(ii):-

95% confidence interval for the mean is determined by

$(x^(-) - t_(0.05,n-1) (S.D)/(√(n) ) , x^(-) + t_(0.05 , n-1) (S.D)/(√(n) ) )$

$( 7.0 - 2.0010 (1.5)/(√(60) ) , 7.0 + 2.0010 (1.5)/(√(60) ) )$

(7.0 - 0.38749 , 7.0 + 0.38749)

(6.61251 , 7.38749)

Final answer:-

95% confidence interval for the mean

(6.61251 , 7.38749)

Answer:

Option A is the answer

Step-by-step explanation:

In the figure attache a solid straight line has been drawn at y = 2 and the area above this line will be represented by y ≥ 2

Similarly area below the dotted line will be y < x

Now area which is common to both is colored area in blue.

So, the system of equations will be y ≥ 2 and y < x

Answers

Both sets of numbers have the same factors:

12 × 12:

= (2× 2× 3) × (2 × 2 × 3)

= 2^4 × 3^2

6 × 24

= (2 × 3) × (2 ×2 × 2 × 3)

= 2^4 × 3^2

Answer:

Step-by-step explanation:

They have the same factors

12x12

6x24

12/2=6

12x2=24

12x12=6x24

For one month Siera calculated her home town’s average high temperature in degrees Fahrenheit. She wants to convert that temperature from degrees Fahrenheit to degrees Celsius using the function . What does C(F) represent?

Answers

We have to find how can someone convert the temperature from degrees Farhenheit to degrees Celsius using the function. The temperature in degrees Celsius is equal to the temperature in degrees Farhenheit minus 32 times 5/9. Or C ( F ) = ( F - 32 ) * 5/9. For example: the temperature is F = 50°; C ( 50 ) = ( 50 - 32 ) * 5/9 = 18 * 5/ 9 = 10 °C. Answer: The function is: C ( F ) = ( F - 32 ) * 5/9.

(15x-5)
35

Geometry set-up
Equation 35+(x-5)
X=
m/WIN

Answers

The given expression is (15x - 5) multiplied by 35. To simplify this expression, we can distribute the 35 to both terms inside the parentheses.

(15x - 5) * 35 = 15x * 35 - 5 * 35

Multiplying each term by 35:

= 525x - 175

Therefore, the simplified expression is 525x - 175.

Please note that the equation 35 + (x - 5) and the term m/WIN mentioned in your question seem unrelated to the given expression. If you have any further questions or need clarification, feel free to ask!Answer:
