taurus [48]

Answer:

a) T test

b) Claim

because critical value is not equal to test statistic then reject null hypothesis

Step-by-step explanation:

Construction of hypothesis

H₀  : p = 75

H₁  : p  ≠ 75

Here Standard deviation = 7

sample = n = 50

Average = x-bar = 78

Level of significance:

∝ = 5% = 0.05

Degree of freedom:

df = n-1

  = 50 -1 = 49

Critical value :

± 1.96

a) T test

test t is  used as average X mean is used

Test Statistic:

t = X₂ - X₁ / Sd /√n

= 78 - 75 / 7/√50

=3.0304

Critical region :

We take two tail T test

test statistic is in reject interval. Reject H₀

b) Claim

because critical value is not equal to test statistic then reject null hypothesis

Find a formula for the nth term in this arithmetic sequence:
Sati [7]

The nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

<h3>What is an arithmetic sequence?</h3>

An arithmetic sequence is defined as a sequence of numbers where the differences between every two consecutive terms is the same  through out the sequence.

The nth term of an arithmetic sequence is expressed as;

an = a + ( n - 1) d

Where;

  • a is the first term
  • n is the number of terms
  • d is the common difference

Substitute the values

an = -7 + ( n - 1) 6

Thus, the nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6
