You have been contracted from a company to do a study. From previous experience with the populations, it is known that the variance for population 1 is 100 and the variance for population 2 is 64. You decide to collect 100 samples from population 1 and found that the mean was 70. You also take 100 samples from population 2 and the mean of that sample is 68. The company has told you that they believe there is a difference in means. a.) Conduct a hypothesis test to find if there is any difference in means with alpha

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

abby has a greater debt becasue she owea 5 more then alan does

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
