Answer:

c. 0.0819

Explanation:

The mean = 0.85

standard error of the proportion is:     sp = sqrt(pq/n)

= sqrt ((.85)(0.15) / 51) = 0.05

P(0.9115 < X < 0.946) = P( (0.9115 - 0.85) / 0.05 < z < (0.946 - 0.85) / 0.05 )

= P(1.23 < z < 1.92)

= P(z < 1.92) - P(z < 1.23) = 0.0819

charle [14.2K]

Answer:

Ms. Fresh loss will be $800 and Basis in new shares is $3,950

Explanation:

Her Loss on sale of stock would be computed as:

Loss = Sale Value - Purchase price

        = $4,800 - $5,600

        = ($800)

As she repurchased the IBIS stock within the expiry of 30 days, she is not allowed to deduct the LTCL (Long Term Capital Gain ) from gain. So, LTCL will be $0.

The basis in new shares is computed as:

Basis = Previous loss + Price paid

= $800 + $3,150

= $3,950

The actual value of adults who play basketball could be 1312.
