@ybhumi It is just an spelling issue here;

await deploy("MockV3Aggregator", {
    contract: "Mockv3Aggregator",
    from: deployer,
    log: true,
    //to get args we should check github or node modulus and serach which arguments are passed in the consturtor
    args:[DECIMAL, INITIAL_ANSWER],

})

here it should be MockV3Aggregator
