Problem $13-3($Algo$)$ Expected value and standard deviation $[$LO$13-1]$

Sampson Corporation is evaluating the introduction of a new product. The possible levels of unit sales and the probabilities of their occurrence are shown next:

$\backslash$table$[[$Possible Market Reaction,Sales in Units,$],[$Low response,$60,$Probabilities$],[$Moderate response,$80,0\mathrm{.}10],[$High response,$110,0\mathrm{.}30],[$Very high response,$150,0\mathrm{.}50],[,,0\mathrm{.}10]]$

a$.$ What is the expected value of unit sales for the new product?

Note: Do not round intermediate calculations and round your answer to the nearest whole unit.$)$

$\backslash$table$[[$Expected value,$]]$

b$.$ What is the standard deviation of unit sales?
