(05.01 LC)  A polling company has decided to increase the size of its random sample of voters from about 3,000 people to about 5,500 people right before an election. A poll was designed to estimate the proportion of voters who favor a new law banning all exterior doors from opening inward. What is the effect of this increase? (4 points)

Alternate span loading is the common loading pattern for determining maximum shear at the supports between the loaded spans due to dead load.
