The correct answer is 'in statistical hypothesis testing, the null hypothesis and the alternative hypothesis are stated in terms of population parameter.

A population parameter is always used to express a statistical hypothesis: The null hypothesis is true if the test statistic's value is within the nonrejection zone.

We look for evidence supporting the null hypothesis when testing a statistical hypothesis. The null hypothesis and the alternative hypothesis are the two variants of the hypothesis that are typically used in research (called the experimental hypothesis when the method of investigation is an experiment).

According to the alternative hypothesis, a population parameter does not equal the given value. Usually, this number is zero, which is the null hypothesis value for an effect of zero.

You can reject the null hypothesis and favour the alternative hypothesis if your sample includes enough evidence to support it.

The z - distribution of the 60% is,

P( -z < Z < z ) = 0.60

P( Z < z ) - P( Z < -z ) = 0.60

The quadratic function f(x) = 3x^2 + 6x – 144  displays the y-intercept of the function.

In the given question, four equivalent forms of a quadratic function are given.

We have to choose which form displays the y-intercept of the function.

The given quadratic functions are:

f(x) = 3(x^2 + 2x - 48)

f(x) = 3(x + 1)^2 - 147

f(x) = 3x^2 + 6x – 144

f(x) = 3(X + 8)(x-6)

As we know that in y intercept form x=0.

A quadratic equation's Y intercept is the location where the graph's Y-axis is broken. This implies that the x axis's coordinates must be zero.

Put x = 0 in the equation to determine the Y intercept in a quadratic equation. You will also receive the Y interception.

Since we have to find the y intercept in the given form so the function

f(x) = 3x^2 + 6x – 144 given in a standard form and y intercept is clearly seen in this function.

The correct answer is the equation of the line is y = [tex]-\frac{2}{3} x - 2[/tex]

Given the equation of the parallel line is 2x + 3y = 3

and the required line passes through the point (3, -4) where x is 3 and y is -4

We can write the given equation  as:

⇒ 3y = 3 - 2x

Dividing both sides by 3

[tex]y = 1 - \frac{2x}{3}[/tex]

On comparing this equation with y= mx+b, thus m = [tex]-\frac{2}{3}[/tex] and the slopes of parallel lines are always equal.

Using the point slope form, we will derive the equation of line

⇒ [tex]y-y_1 =m ( x- x_1)[/tex]

⇒ [tex]y- (-4) = -\frac{2}{3} (x-3)[/tex]

⇒ [tex]y+4= -\frac{2}{3} (x) - \frac{2}{3} (-3)[/tex]

⇒ [tex]y = -\frac{2}{3} (x) +2-4[/tex]

For the stated question-

Thus, the volume of sphere is found by the equation.

Volume of sphere V = 4/3 πr³

V =  1611 cm³.

The length of the line segment x equals half the height of the triangle.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a right triangle  is a triangle in which one angle is a right angle, i.e., two sides are perpendicular. Trigonometry is based on the relationship between the sides and various angles of a right triangle.

Side an is the side adjacent to angle B that is opposed to angle A, whereas side b is the side adjacent to angle A that is opposed to angle A.

If the lengths of all three sides of a right triangle are integers, the triangle is said to be a Pythagorean triangle, and its side lengths are referred to as a Pythagorean triple.

The proximal tubule reabsorbs all of the filtered glucose and amino acids, as well as salt, chloride, potassium, and bicarbonate. Additionally, sodium ion and glucose were co-transported in the proximal tubule by the co-transporter SGLT (sodium dependent glucose transporter). The ability to transport glucose distinguishes two SGLT (SGLT1 and SGLT2). Since SGLT2 is abundant in the S1 and S2 segments of the proximal tubule and SGLT1 has a high affinity for glucose, it filters 90% of the glucose. Option (b) is correct, therefore.

Option (a) is False, since the distal tubule is crucial to maintaining a healthy acid-base balance. The amount of extracellular fluid is regulated.

The descending limb of the Henle loop, which is involved in reabsorption of salt, urea, and water, makes option (c) incorrect.

Maxima of a function gives the maximum value of the function in a given interval or in the whole domain.

Let the length of the rectangle be l m and width of the rectangle be w m

Perimeter (P) = 2(l + w)

By the problem,

2(l + w) = 72

l + w = [tex]\frac{72}{2}[/tex]

l + w = 36

w = 36 - l

Area (A) = l [tex]\times[/tex] w

A = l [tex]\times[/tex] (36 - l) = [tex]36l - l^2[/tex]

Differentiation with A with respect to l

The pressure is assessed through the ideal gas equation and Dalton's law

Partial Pressure of hydrogen gas in the gas collecting tube can be calculated as:

According to Dalton's law, the total pressure of the system will be the sum of partial pressure of all gases

In the system, the pressure is exerted by the water and  gas.

Total pressure = P(water) + P(Hydrogen)

P(hydrogen) = 746 mm Hg (given) = 19.8 mm Hg +

P(hydrohen) = = 746 mm Hg - 19.8 mm Hg

= 726.2 mm Hg

So, the partial pressure of Hydrogen was found to be 726.2 mm Hg.

To calculate the volume of hydrogen at STP, ideal gas equation is used.

For this, we calculate the moles of Hydrogen in given conditions:
