5, 4 7/8, 4 9/10 in order least to greatest
Klio2033 [76]

The order from least to greatest is 4 7/ 8, 4 9/ 10 , 5

<h3>What are fractions?</h3>

Fractions are simply representatives of part of a whole.

The types of fraction are;

  • Mixed fractions
  • Simple fractions
  • Improper fractions
  • Proper fractions

From the information given, we have to arrange in order from least to greatest

5, 4 7/8, 4 9/10

Turn mixed fractions to improper fractions;

5, 39/ 8 , 49/ 10

From least to greatest is written thus;

39/ 8, 49/ 10 , 5

Thus, the order from least to greatest is 4 7/ 8, 4 9/ 10 , 5

Use the standard norml distribution or the t-distribution to construct a 99% confidence interval for the population mean. Justif
dalvyx [7]

Answer:

E) we will use t- distribution because is un-known,n<30

the confidence interval is (0.0338,0.0392)

Step-by-step explanation:

<u>Step:-1</u>

Given sample size is n = 23<30 mortgage institutions

The mean interest rate 'x' = 0.0365

The standard deviation 'S' = 0.0046

the degree of freedom = n-1 = 23-1=22

99% of confidence intervals t_{0.01} =2.82  (from tabulated value).

The mean value = 0.0365

x±t_{0.01} \frac{S}{\sqrt{n-1} }

0.0365±2.82 \frac{0.0046}{\sqrt{23-1} }

0.0365±2.82 \frac{0.0046}{\sqrt{22} }

0.0365±2.82 \frac{0.0046}{4.690 }

using calculator

0.0365±0.00276

Confidence interval is

(0.0365-0.00276,0.0365+0.00276)

(0.0338,0.0392)

the mean value is lies between in this confidence interval

(0.0338,0.0392).

<u>Answer:-</u>

<u>using t- distribution because is unknown,n<30,and the interest rates are not normally distributed.</u>
