Answer:3.67,1

Explanation:

TE = (O + 4T + P) / 6

where,

TE = Pert Expected Time Duration,

O = Optimistic estimate, =2

T = Typical estimate,=3

P = Pessimistic estimate=8

TE = (O + 4T + P) / 6

=(2+4*3+8)/6

3.6666=3.67

σ = (P – O)/6

=(8-2)/6

=1

jarptica [38.1K]

Answer:

A) change in the cost of eating index = <u>20% increase</u>

B) Suppose that consumers are completely indifferent between two chickens and one ham. For this example, how large is the substitution bias in the official "cost-of-eating" index?

The <u>INCREASE</u> in the cost-of-eating index is <u>18</u> %.

The <u>OVERESTIMATE</u> of inflation in the cost of eating reflects substitution bias.

Explanation:

2015

product               units              unit cost               total

chickens              30                      $4                   $120

hams                    10                      $5                     $50

<u>steaks                  10                      $8                     $80</u>

total                                                                       $250

2016

product               units              unit cost               total

chickens              30                      $5                   $150

hams                    10                      $7                     $70

<u>steaks                  10                      $8                     $80</u>

total                                                                       $300

A) ($300 - $250) / $250 = 20%

B)

if consumers are indifferent for 2 chickens per 1 ham, then the new basket should be assuming consumers will purchase the cheapest option:

2016

product               units              unit cost               total

hams                    25                      $7                   $175

<u>steaks                  10                      $8                     $80</u>

total                                                                       $255

the increase in inflation would have been = ($255 - $250) / $250 = 2%

the substitution bias = reported inflation - real inflation = 20% - 2% = 18%
